Sporty watch is bound to lead the fashion trend , personalized in the intensified life, diving watch with its rugged housing , the ability and the depth of water sports personality profile to attract more and more modern . I always look forward to diving watches reveal why so much charisma , and occasionally wondering how this works. After long-term comparison and observation, I concluded that most of the dive watches modern invisible followed the rules . Despite many exceptions , but the rules outline the contours shift the diving watches have a clear picture .
Rules of a Case
For the diving watch , the water is the most critical case for structural design . Diving is proud of the outstanding waterproof structure , its peculiarities is the case , the shape and structure . In the early twenties had begun exploring a number of brand waterproof structure , after all, was able to watch with waterproof function is handful . The structure of the water was only required to use the watch as swimming , so the structure and design is relatively modern dive watches appear not mature enough .
However , due to technological advances and bold designer watches in the late twenties still design a representative waterproof structure, in which case most famous is the two-tier structure . In fact, the principle of two-tier structure is to redesign the existing watch a good waterproof case . At that time, the most well-known brands Rolex and Omega Manufacturing Marine Manufacturing of Pre-Oyster adopt a double- case design, but form the structure are quite different . Rolex uses a circular shell, while the Omega was chosen square shell structure . Unfortunately, this design is not ideal waterproof structure, Rolex introduced the late twenties century under the influence of water-proof shell structure 11 " Oyster " case ! It can be said modern diving watches are constantly exploring and previous design based on continuous improvement , and oyster -like structure into the later case the major brands produced Diving pioneer shell structure .
Thus , modern diving the most significant features of the watch are more or less similar is the case are manufactured using one . Through strong and professional design shell structure , while improving the back cover and the crown office , after sealing , as the dive deeper , more durable dive case . Depth of water over 300 meters of the dive watches are used most of the locking screw locking crown and screw the bottom cover , the three most likely to feed through for the site were made, be assured that reduce gap , increase The role of sealing effect .
Therefore, the first diving watches together to create one similarity is that the massive case and screw locking crown, screw locked back cover of the structure .
Rule 2 Shoulder
Shoulders do not remember the first structure is the brand which pioneered , but still able to see whether it is formal or sporty watches often use the shoulder of the structure . A friend asked me who shoulder the biggest role? I was surprised to tell the watch with many luxury watches friend 's shoulder is decorated with the current role .
Several days later , a friend who once taught to finally point out that my fatal mistake. Indeed, the shoulder ! As the name suggests , it is to protect the crown from touching the " shoulders . " For the dive watch , this design is more practical and effective , you can imagine the screw locking crown despite pressure than normal -in the crown is more durable and waterproof , but still in use will be offset by friction or external forces which occur Injury occurred . Shoulder structure very effectively protects the crown from the impact of external forces , in particular paragraph in the movement is the most common , it is commonplace in the dive watches .
Therefore, the general features of diving watch is the second location in the design of the crown has a protective effect of the shoulder.
Rule three crown
No doubt , did Case structure, the second time I also mentioned separately to the crown , the title will be listed as a major one . Because the water structure is not just only a waterproof screw -type locking structure . Early in the fifties or so , the U.S. started trying occasions a " cork " stylesheet crown architecture , structure , and unfortunately Zhe Yang De Bu Neng Shen Du waterproof protection , in particular, the diving deeper Gainian Duiyuzhuiqiu for people who they would choose Gengyou Personality, more type design.
In addition to locking screw -type crown structure , Panerai is the first of its kind and unique to create a generation of one of the pioneers . Panerai designed the original bridge rod locked crown structure , and in 1953 obtained a patent . Bridge rod locked crown structure is designed to be a special crown locking device , the structure has the makings of modern technology , then this crown will be installed in the early 40 's waterproof Panerai elevated to 200 km Feet or more ! The modern Panerai Luminor series dive watches are the functions of waterproof 300 meters , while the matter is after 400 meters on the occasion of testing . This device has become one of the Peinahaite some signs .
In addition, Cartier 's PASHA series and Hamilton 's Army watch , etc. , in the original plain crown, another addition to the design of a screw -type protection of the crown , screw case this envelope in addition to their crown Inferior race to improve the waterproofing ability to watch after all, a unique design.
In any case, in fact different crown structures are the most prone to water ingress protection , and thus, almost all of the diving watches more than three designs will be chosen , particularly the structure of screw crown masses !
Rule four bezel
All true professional diving bezel almost all the design using one-way rotation , and watch turning circle must be counterclockwise ! Used in the diving watch ring , every minute, every five minutes of the scale are able to clear ! This design is based on 11 of course it is in accordance with ISO 1981 the requirements for the dive watch , dive watch as ISO international standards . Scale in order to increase the watch in the dark circle in the identification of the deep sea , often configured in its 12 o'clock position , a luminous point , to record start time.
When the rotating ring diving can hear " blah , " the voice of rotation , will form a large circle luminous point of targeting the location of the start time minute hand , unidirectional rotating bezel is also to prevent the clockwise rotation of the errors caused by time Reading , quite practical . Many players love the watch on the dive is actually part of the one-way rotating diving bezel can be obsessive , with a rotating bezel can watch nature more fun !
General professional dive watches are used external bezel design , the IWC Aquatimer Cousteau ingenious design is a unique one-way rotating bezel with built-in time , so the design was to protect the watch after the water without Joint clean-up within the case bezel sediment . Due to the unique character of the design is loved the world , so many other brands have followed suit.
For gamers , a dive watch , in addition to compare the depth of the diving interesting concept , in fact, is really playable one-way rotating bezel that . Because we all know that we can not go very deep deep place nominal .
Rule five watch Mirror
In the deep sea , as the visiting hours but is responsible for isolation between the case and the water watch is a mirror . Imagine the depth of the seabed in 300 m , the watch will mirror how much pressure to bear . Through scientific calculation , diving watch mirror and case thickness is a certain percentage , so we often find that the deeper diving watch , it 's case and watch mirrors are thicker !
As technology advances , almost all of the modern watch with a sapphire crystal all of this material not only in the ordinary occasions more wear-resistant hard , but also after the anti- reflective coating on both sides inside and outside the process , ensuring the role of increased permeability . The so-called AR , to put it simple point is increased visibility , especially in the sea. Such as the Breitling Superocean Steelfish X-Plus uses a 3.7 mm thick double- coated sapphire crystal , and only with sufficient thickness to withstand the watch mirrors the pressure from the deep sea , just 3.7 mm thick long beyond an ordinary The thickness of the movement .
Therefore, the rules of five diving watch is a watch with sufficient thickness mirror.
Rule six Luminous
Dial and the luminous bezel divers in deep water diving is the survival of the most important features, one of the light in the dark capabilities necessary functions into one diving watch . On ordinary watches often used the fluorescent materials to improve night reading Neng Li , and Duiyu dive watch is not only required for the luminous features and functionality of materials and Yeguang good or bad will it Chansheng to Guan Qian Shuiyuan critical impact . Therefore , most modern diving watches to scale , gauge needles are designed to become a large scale and oversized clock minute hand display . In addition to large scale gauge needles and luminous , the most important is the rotating bezel can be zero on the scale of the luminous start , the location of the luminous display watch for diving is critical .
Luminous materials development is also changing with the times , the early radium luminous material (Radiomir), because of its contained excessive radiation was discontinued , replaced by deuterium (Trituin Luminor). For the human body , safety is most important , in addition to reading to ensure a good night , most of luminous material used type of Luminova afterglow luminescent material . Of course, the intensity of light after a certain period will have a decay .
In the luminous material application and design, Ball opened up a new path. Ball control watch used as a pure B radioactive tritium tritium , the inner wall coated with fluorescent material , the use of tritium B -ray excited luminescence , B rays can not penetrate the wall , as long as the tritium tubes are not broken on the sound . This light design than the previous two brightness and luminous persistence much stronger science and technology makes the modern technology has made leaps luminous .
As for the diving watch , regardless of what kind of luminous materials or design, but the luminous display is essential.
Seven row helium plant rule
Professional diving watches for technical issues to be resolved is one of access to deep water in the pressure to squeeze into the form of the watch after the release of gas , because when the watch due to internal pressure is higher than before the water will result in case of external damage fragile Department . Study , watch as the submarine left the high pressure will be due when the internal gas decompression and dealt with, and lead to the release or broken glass . To solve this problem , the depth of diving watches specially designed exhaust valve .
The first exhaust valve , or as rows of helium valve is with the French in 1967 Rolex Comex diving expedition co- developed . The precision of the exhaust valve functions with automatic row helium , when the dive watch from high-voltage submarine will change under the pressure surrounding the internal pressure of the gas discharge certain . Rolex Sea Dweller in the later series are widely used , and water capacity of incredible 3,000 meters Breitling Sea Wolf series has also adopted this classic design . Omega Seamaster series of well-known is the 10 o'clock position designed a special crown , in fact, this is a manual exhaust valve . Of course, I always understood that the design although some superfluous , but after all cool , right?
The nations of the Aquatimer Cousteau 2000 once again demonstrated its independence in the diving area of special line of the watch 's personality, it is a material produced by the titanium case , the use of composite materials to build a unique patent -free valve structure , so divers can reach 2000 meters Aquatimer Cousteau actually no row with the helium valve structure , indeed astounding.
Despite the row of helium device is not essential for each dive watch design , such as can dive up to 500 meters Breitling no row helium device, while the Omega 300 meters in the diving section on the watch a row of specially designed helium valve Undeniably, however, to a depth of professional diving watches , this device is very important.

Jaeger: Typical Swiss Watch Brand
Jaeger watch is a typical Swiss brand name watches . Many Swiss watch brand has the following two characteristics : from the Jura mountains JOUX valleys , such as Piaget; two crystallization of collaboration , such as Patek Philippe (from 100 up to PATEK and Philippe PHILLIPE create two ), Chi Pak (from Grardt and Perregaux collaboration ) and so on . Two features of both , then enjoy a great reputation in the world such as the Audemars Piguet and the Jaeger watch and so on .
18th century , Britain and France watch manufacturers monopolized the watches and clocks , for the merchant to provide precision timer , support their navigation around the world. At the same time , another force is also active in the pipeline clock , this is Switzerland, because a large number of Protestants in France craftsmen to escape religious persecution , hermit in the mountains of JOUX Rui Shiru La valley . Six months a year there are snowbound mountainous , long winter people staying at home and have enough time and patience to create a more sophisticated mechanical devices , such as music boxes, clocks and other machinery and automation . To the 19th century , known as the "Combiers" valley residents , already has more than Britain and France and other countries watch technology, the rest of the world catch up .
Jaeger watch that is born in this valley . LeCoultre family in 1803 gave birth to a boy Antoine, he began as an apprentice in his father's smithy , and devote ourselves to research gear manufacturing technology and metallurgy . In 1833 , he founded the town in Le Sentier hand field, left the family business . By 1860 , his company's size has reached more than 100 people , specializes in watches precision devices, has introduced hundreds of watch movement, which established themselves in the position of the Swiss watch industry . 1903 , Antoine100 years old (of course he did not live up to that time , but he did receive a Best 's birthday gift ) , and his grandson Jacob - David, when speaking with the French precision navigation device manufacturers Jaeger- Edmon Jaeger cooperation , the establishment of today's Jaeger watch plant .
Founded from 1833 to present, families have many patents , the development of the world watches to make a great contribution . As the Jaeger is extremely diverse movement of production , is the world's few movement Output tabulation company . This is a movement , especially in high-end , a number of other brands of high-end watch as sales of small, so their movements are too few output will be selected Jaeger produced the movement , virtually made a home for positive publicity . Also considered it mutually beneficial.

The Classic Facet of IWC Watch
IWC is an American young Americans Foluolunting . Ariosto . Jones was founded in Schaffhausen in 1868 established his watchmaking has been the essence of the enthusiasm and co-exist with , and in Portugal, Jones series In perfectly vivid . That year, Jones created a 6 pocket design for different basic movements , these movements are very good quality , but all have the famous " Jones arrow "design - three-quarters of the host to extend the pointer to the version in order to accurately Adjusted accuracy ; movement to name Jones and Hang Yu in the history of watchmaking . Today , IWC Portuguese Jones watch the world produces only 500 platinum , 18k rose gold , and only 1,000 of 3,000 stainless steel, limited edition , as collectors rush to buy the watch 's treasures.
Latest Engineers IWC watch series is now available in stores . Engineer Series with type extra watch and practical function , built-in advanced movement techniques every time ; new series can be traced back to the family of engineers, a pioneer in the design and the accumulation of years of experience to achieve the milestone. IWC developed a new model 80110 automatic movement watch their place within the family of engineers , with soft iron inner shell (which can resist the magnetic field up to 80,000 amperes ), Buhler Dayton automatic winding system and a high degree of shock devices on the market No other than the extravagant can automatically watch .
1868, IWC introduced the first pocket watch , and since then , IWC Swiss watch industry in many ways to obtain a special status , while the world watches manufacturing industry also plays a decisive role .
IWC agents around the world, the efforts of the past three years, grown up to 500 percent performance , results quite amazing , even more devoted in making Plant , expand the Asia Pacific market. Basel in April 1998 released a new watch is the first step more in March that the first appearance in the Asian region , to be published telex video shows IWC focus on the Asia-Pacific region .
IWC first set up shop in Las Vegas and Dubai in the United States , Hong Kong is Asia Pacific 's first shop in the city of IWC , in the July 20, 2005 will kick off within this year the brand also plans to set up four Asian Shop .
Tough to black people , white and gray tone reinforces the theme of IWC : "IWC is a watch manufacturing engineers "; brand stores low-key style with the design of echo to each other . IWC has created a specialized shop the best environment for customers to enjoy can be focused exclusively adhere to IWC 's watchmaking philosophy of "Probus Scafusia" ( from Schaffhausen 's extraordinary technology and exquisite craft ) manufactured fine watches . The shop " with a depth of simplicity "(Complex simplicity) design features the image of another closely linked with the IWC , in every corner of the shop to show it. Elegant , simple lines with beautiful high quality glass and metal , so that every passer-by to enjoy the attention cast more tempted to enter the garden and watch experience unusual feelings .
IWC stores offer customers the most comprehensive and high quality services watch series , and this year SIHH watch show of the new products include Portugal Jones series (Portuguese FA Jones Collection) and engineers Series (Ingenieur Collection), will take the lead in the IWC specifically Store display . In addition , a series of limited edition models also be evil : outstanding complex with watch (Grande Complications), Portuguese Tourbillon (Portuguese Tourbillon Mystere) and Portugal 3 Q watch .
IWC Schaffhausen , a wealthy founder of the pioneering spirit of Americans . From the beginning of 1868 , this leading Swiss watch factory has been the development of watchmaking , and constantly watch industry is extremely complex and sophisticated creation of new standards. 10000 State watch is known as " high-end watches engineers , "said , specializes in manufacturing men's watch . Classic style with clever design , elegant and sophisticated , the operation is extremely simple - this is the famous nations watch .
The dial is inscribed with " Schaffhausen IWC , "but between the world-famous watch factory has chosen a rural town in the Rhine factories , and many people are puzzled . As the site away from the famous Swiss watchmaking center , together with the nations watch company (International Watch Company) does not like the name of Swiss company to make people curious about their origins . American youth from the Boston Foluolunting ‧ ‧ Ariosto Jones (Florentine Ariosto Jones), is a rich pioneering spirit , lofty aspirations and sensitive antennae of the tab master of business . When the boat across the Atlantic , his mind has a perfect plan . He uses modern American production machinery to a very accurate pocket watch movement, and at the time in low-wage economy era Swiss clocks set off a revolution . Jones in 1868 in Schaffhausen venture , set up the nations form the company , the local became the cradle of watchmaking innovation and precision . Not far from the Rhine Falls in place , this new tab to modernize production plants use water .
Jones , founder of the pioneering spirit , passion, vision, laid the nations form the cultural foundation plant . Engineers on the watch in terms of nations , watches itself is more fascinating than the precise time , they like the idea of bold innovation , precision and innovative efforts to delve into the design, therefore , 130 years, the nations watch watch industry made great contributions to the development of . In the professional field of watchmaking technology , Schaffhausen innovation process, so watch enthusiasts praise . IWC watch , including superb original complex watches series, Da Vinci watch series, and the Portuguese watch series . Pilot watch series, watch series and marine engineers Chronograph series are of a traditional watch -hours . The family watches with sport / practical design , coupled with stainless steel or titanium case , the most suitable for everyday wear sports -loving.

The way to identify the real/fake watch by letter identification
Many people , including even the maintenance of the master clock to do , do not watch carefully paid attention to the letters on the plywood logo . If an imported Swiss brand of watches, the movement must have some letters on the plywood logo , which typically includes :
1, movement manufacturers (eg : ETA)
2, movement models (eg :2824 -2)
3 , the patent marking (PATENTED)
4, the number of movement drills (such as 25 JEWELS)
5, production of the country (SWISS)
6 , watch plant -specific markers
7 , there will be expensive watch movement production number
8 , Geneva luxury watch movement will be identified
9 , expensive watches is a watch movement are detected by which certification mark (eg , watches in three temperature and five positions after the next check )
10, watch brand or trademark of the letters (usually printed on the automatic Tuo )
11, precision tuning identification of other (usually printed on the splint placed on )
Generally speaking, the more complex and expensive watches, the more movement on the identification , fake brand watches often can not do at this point . So, this is one way to judge the authenticity of watches .
Typically, the splint on the lettering is more difficult , and can only be a good moment before the finished products , and in particular the automatic Tuo on bad lettering, which I heard some tungsten alloy material , ( all with a large proportion of the metal) Not stamping . So, leave the watch to forge the identity of the original brand watch , can only be a thin metal film , to better identify the first moment then glue stains to automatically Tuo above , but also useful for laser printing .
I have also seen Patek Philippe Patek pilippe false watch , also spared no expense in the movement up plywood lettering . But the font size and color are done, the font is too large partial dispersion , color and style of the watch is not really unified .
As we all know , ETA movement is now a different watch cards are using it . So , not only the movement to determine the number of the authenticity of the watch . I have said above (Article 6 ) of different brands have their own unique form plant markers , for example : ENICAR splint in the main movement stamped (or press ) the letters AR , which is a PH of TITONI Words , this is our watch to judge the authenticity of an important basis.

The Way to Adujust The Watch Calendar and Weeks
Watch Some basic debugging methods and precautions are as follows :
1 . week and the calendar can not be 21:00 to 3:00 tune , so it hurts the watch . Calendar of beating a gear -driven , so are generally slow jump .
2 . weeks pointer is automatically updated . Date and week are jumping at the zero word , this accuracy appears only in the electronic watch , pointer watch less accurate . may advance or postpone the date and week jump since the word is a wheel to drive , if Also jump words , then drive requires a lot . So, for separate , general -week change in the dates will change after the half to skip a few hours .
3 . watch the date of 11 o'clock , 12 o'clock , 13 o'clock jump only solution : as long as the clock turn clockwise to a week , and then resetting the date on it.
4 . the middle of the adjustment knob two- block , the first block is to adjust the date, the second block is to adjust the time . The first block adjustment, rotation is transferred later date ! ( If the watch does not have weeks of shows , then do not need a week to set ) forward rotation is transferred weeks.

What Factors Will Affect The Timing Precision of Mechanical Watches
Mechanical precision of the watch travel time by many factors, in general , primarily the following eight factors:
1, external influences
Is the impact from various external clock , depending on clock work environment. Often used measures are: shock design , waterproof design, magnetically shielded design, additional protection shell. Precision navigation is often used on the bell joint, so that navigation can be maintained in the clock in the rough level .
2, Friction
Friction usually have both positive and negative effects , it has the positive side , such as the points of friction wheel , automatic watch springs and friction between the article box , screw locking , etc.; the other hand, the friction will lead to lower transmission efficiency And wear parts , thus affecting the timing . Common solution: to improve lubrication conditions , according to different requirements , use of different lubricants ; with stones bearing or gasket ; improvement of the tooth surface conditions, including the use of scientific and increase the conjugate tooth surface finish , etc. , but in general Tooth surface without lubrication (in this case, the lubricant viscosity may be higher than the resistance generated by friction ) .
3, speed needle
Speed when the needle is an easy- economic structure of school , but the theory and practice has proved that it will affect the system , etc. , which also may have potential difference , the relatively large random timing error , can not compensate for or offset . Solution are: minimizing the distance between internal and external speed needle ; but the best way is to not speed needle , by adjusting the balance wheel 's inertia to adjust the speed , such as Rolex 's Mircro stella -conditioning system .
4 , escapement
Escapement body of an energy transfer process mainly on balance wheel hairspring system impact Bailun springs system Zhi Youzai free vibration situation, Caineng Weichiguding oscillation frequency , Xianran , capture vertical organization will affect the energy transfer Oscillation frequency . Theory that the process of close to balance transfer balance , this effect will be reduced . Solutions are: using precise escapement , such as claw -type escapement , the energy transfer process which occurs at the equilibrium point , the angle of impulse transmission is very small , impact is small, but it 's a one-way transmission impulse to Balance spring system has more freedom to shocks space ( on this point , the relative error can be reduced by half !) . Of course, the Swiss lever escapement with style and good technique , easy to adjust the merit of the mainstream of the international mechanical watch escapement , but the design should minimize the angle impulse transmission . Swiss Omega company reduce the escapement on the basis of time , introduced the coaxial escapement , this is the invention of the United Kingdom , Dr. George Daniel , but the principle point of view, it is leveraged escapement and claws Mixture of type escapement .
5, temperature
The major impact of temperature in two ways : First , temperature changes will work gossamer length , while changing the inertia wheel pendulum can directly affect the timing accuracy; Secondly, the temperature change will affect the oil 's viscosity, affect the transmission efficiency Thus affecting the timing . This can take the following approach : using open bi-metallic balance wheel hairspring temperature compensation system ; the use of special alloy materials and the balance hairspring so that the temperature in the work area (8 ° -38 °) have a certain temperature compensation ; use mobile speed Needle temperature compensation . Standard lubricants , for extreme temperature conditions , such as Omega 's moon watch , with no lubrication or solid lubricant .
6, magnetic field
The most influential gossamer magnetic field can change the modulus of elasticity, also gossamer effect of the magnetic field deformation , resulting in additional stress , serious , the magnetic field can lead to gossamer adhesions , serious impact on travel time . The solution is : The anti-magnetic materials .
7, gossamer balance
General swing box springs , its center of gravity with the balance wheel swing angle change, the force of gravity , it will produce position error . The solution is : The Breguet hairspring , central contraction, the focus does not change with the tilt angle ; the end of the curve by Philip cylindrical hairspring and use of upper and lower symmetry ; using linear springs ; history that someone has used ball springs , superior performance , but the technology is poor Few practical applications .
8 balance
Balance components directly affect the balance bit poor balance components of static balance is a basic requirement .
If the above factors are ideal , Shiyou go watch more stable , through the watches of the dynamic balance can be integrated to improve walking performance . There is a very special way : principle is that when the balance wheel swings up to 220 degrees , all passed to balance the momentum of the frequency of no effect , it has been used to install in the balance wheel escapement force agencies to control the pendulum Increase to 220 in the vicinity , which was an idea.
1, external influences
Is the impact from various external clock , depending on clock work environment. Often used measures are: shock design , waterproof design, magnetically shielded design, additional protection shell. Precision navigation is often used on the bell joint, so that navigation can be maintained in the clock in the rough level .
2, Friction
Friction usually have both positive and negative effects , it has the positive side , such as the points of friction wheel , automatic watch springs and friction between the article box , screw locking , etc.; the other hand, the friction will lead to lower transmission efficiency And wear parts , thus affecting the timing . Common solution: to improve lubrication conditions , according to different requirements , use of different lubricants ; with stones bearing or gasket ; improvement of the tooth surface conditions, including the use of scientific and increase the conjugate tooth surface finish , etc. , but in general Tooth surface without lubrication (in this case, the lubricant viscosity may be higher than the resistance generated by friction ) .

Solutions are: using precise escapement , such as claw -type escapement , the energy transfer process which occurs at the equilibrium point , the angle of impulse transmission is very small , impact is small, but it 's a one-way transmission impulse to Balance spring system has more freedom to shocks space ( on this point , the relative error can be reduced by half !) . Of course, the Swiss lever escapement with style and good technique , easy to adjust the merit of the mainstream of the international mechanical watch escapement , but the design should minimize the angle impulse transmission . Swiss Omega company reduce the escapement on the basis of time , introduced the coaxial escapement , this is the invention of the United Kingdom , Dr. George Daniel , but the principle point of view, it is leveraged escapement and claws Mixture of type escapement .
5, temperature
The major impact of temperature in two ways : First , temperature changes will work gossamer length , while changing the inertia wheel pendulum can directly affect the timing accuracy; Secondly, the temperature change will affect the oil 's viscosity, affect the transmission efficiency Thus affecting the timing . This can take the following approach : using open bi-metallic balance wheel hairspring temperature compensation system ; the use of special alloy materials and the balance hairspring so that the temperature in the work area (8 ° -38 °) have a certain temperature compensation ; use mobile speed Needle temperature compensation . Standard lubricants , for extreme temperature conditions , such as Omega 's moon watch , with no lubrication or solid lubricant .
6, magnetic field
The most influential gossamer magnetic field can change the modulus of elasticity, also gossamer effect of the magnetic field deformation , resulting in additional stress , serious , the magnetic field can lead to gossamer adhesions , serious impact on travel time . The solution is : The anti-magnetic materials .
7, gossamer balance
General swing box springs , its center of gravity with the balance wheel swing angle change, the force of gravity , it will produce position error . The solution is : The Breguet hairspring , central contraction, the focus does not change with the tilt angle ; the end of the curve by Philip cylindrical hairspring and use of upper and lower symmetry ; using linear springs ; history that someone has used ball springs , superior performance , but the technology is poor Few practical applications .
8 balance
Balance components directly affect the balance bit poor balance components of static balance is a basic requirement .
If the above factors are ideal , Shiyou go watch more stable , through the watches of the dynamic balance can be integrated to improve walking performance . There is a very special way : principle is that when the balance wheel swings up to 220 degrees , all passed to balance the momentum of the frequency of no effect , it has been used to install in the balance wheel escapement force agencies to control the pendulum Increase to 220 in the vicinity , which was an idea.

The Working Element of Mechanical Watch Spring
Clockwork is to provide energy for the watch parts . circle around the box in the article . Article axis milling using side groove of a wound . Article axis side groove driven by the article body . Watch on the article in the absence of complex cases, which can take about 36-50 hours when . As the winding withstand significant stress , often lead to fracture of the present, the use of alloy material , so that winding little break . Clockwork save some energy , to even a small number and assigned to the oscillator . To this end, the energy provided by round out group by group to wheel out the same proportion to reduce transmission power and increase turns . Round out the group includes four wheels and four gear , after three rounds is the riveting pressure on the first three gears . In the diagram , the slash that engagement between the moving parts , while the horizontal line indicates the same axis actuator was riveting . The first round is a circle milling only the box section wheel . The last one is the escapement gear wheel , escape wheel Riveting on the gear . Escape wheel and the counter is assigned agencies . Article box rotary circle about 6 hours, during the interim period , escapement and escapement gear rotation cycle of about 3600 . This figure represents only the first round and final round of a frequency ratio between the rotation . The percentage of this value is always in range. Generally managed to gear and sub- round in the watch center, and the rounds per hour .
If you can not read above a mess , then look at this : winding through the chain of action (whether manual or automatic ) aggregation of energy , and then drive the energy transmitted to the escapement , escapement uniform separation of the energy , Then go through the drive system and the pointer display time.

Several Errors in Watch Using
When using the watch there is often a few errors :
(1 ) wear a watch sauna , completely wrong behavior.
Because no matter how much water depth in meters, not to sauna , may know the time will not have any internal appearance , in fact, the movement has been infringed . Because of the appearance of pieces of watches from the expansion coefficient of materials of different composition , if worn folding watch temperature greater than or equal to 50 degrees , the watch will have a pressure difference in air pressure , the watch of the air will run out When the temperature difference reduction , the outside air is back to the watch . Steam bath in the temperature much higher than the standard form of the air will run out when the humidity higher than standard air , and some may not immediately appear when the form of water vapor , but Tuyu low temperature than the temperature of the watch Standard air will condense on the glass , the formation of water droplets or fog , and steam heat will accelerate the aging waterproof apron can not properly protect the movement .
( 2) The condensation of water droplets as sapphire crystal lens to confirm the watch ;
This approach is unscientific practice , because some minerals will also drop glass condensation , and some water droplets on the sapphire crystal will spread , but the same degree of wear , watch mirror material for the factory which will be described , Do not use drops to try .
(3 ) quartz watch after the battery is no longer waterproof changed his , and travel time was not accurate : this view is wrong.
Specialized maintenance equipment is perfected, who changed the battery you will use professional equipment by a professional technician to re- suppressed , re- established water , travel time measurement error is within the normal range . So be sure to change the batteries in the professional maintenance station .
(4 ) with the friction surface , the glass watch wear and other acts confirmed , but we do not recommend customers to experiment with destructive behavior .
While other high-tech ceramics with high anti-wear , but fragile, wrestling and crashing.

How to Identify Counterfeit and Fake Watch
Modern clocks are precision machinery industry and microelectronics industries crystallization . Polish brand watches in the world , the less there are thousands . According to their quality and price points , is that high , medium and low categories , but also really well-known within the hundred . Currently displayed name brand watches have been 1 to 2 years of history .
1,brand counterfeiting :
Generally occurs in high-grade fake brand name brand , because the availability of high profits . In trademarks, the original studio pieces of letter products , manufacturing was the same, rough look impeccable . With packaging, manuals, birth certificate and complete everything . But the watches and brand selection is not supporting the movement , or poor grade parts selection . Lower cost of production of the brand . Often in internal sales , prices are much lower than the original brand , but still highly profitable. In some watches do not detect sound irregularities in the city and shopping malls have sales , allowing users to suffer great loss surgery . In the domestic market once there fake Rolex , fake radar, watches and other false FIYTA .
2,the appearance of counterfeit items
At present the appearance of items in the watch in the proportion of high prices . If the French production of " Cartier " watch , price 3.52 million yuan . Xiang natural diamond , 36 carats, 60,000 yuan per carat basis, the optical coordinates of the more than 200 million diamonds . Therefore, the appearance of counterfeit items should be reproducible , mainly the following aspects:
(1 ) natural diamond factory , artificial diamonds, diamond (glass drilling ), etc. to identify and counterfeiting : all objects of natural diamond factory is the most hard , as 10 hardness ; man-made diamonds one of 8 to 9 ; diamond ( Glass drilling ) than the hardness of natural and man-made diamonds is low, and fragile . Artificial diamonds and diamond prices are cheap , each piece is only 0.1 to 0.2 yuan . Therefore, the purchase of plants with natural diamond watch , be sure to pay attention to authenticity was not to fall for . Testing when necessary to the relevant departments .
(2) K gold plating , gold plating acid identification and counterfeit : K gold, gold-plated , gold -plated
surface of acid yellow colors are not easy to distinguish , but also easy to fake . If K gold shell : have 10K gold , 14K gold , 18K gold and other differences , in the absence of case detection equipment is difficult to distinguish . Some even pretend Dou K gold plated shell shell . In addition, the gold shell thickness of the plating layer is difficult determination . Some 3 -micron gold-plated watch indicate the actual even 1 micron do not , watch more than a year using a gold turned black , and even lost their ability to rust , so when customers buy gold watches to ask clear, because the mall has Provisions do not guarantee the appearance . Of course the expensive gold K shell can not easily fake , but the proportion in gold than have others.
(3 ) fake glass watch : watch currently in use , as described earlier , there are three glass : glass , ordinary quartz glass, sapphire crystal glass . Confusing and difficult to distinguish the quartz glass and sapphire crystal glass . Both in quality and price vary widely . Sapphire crystal glass was once known as " never wear glasses " , now changed to " hard to wear glasses . " Its price is about ten times the conventional quartz glass , so only high-grade watches in the middle of rock crystal with Lan Fu . Sales over the past fake Rolex , his sheet glass ordinary quartz glass . Ordinary quartz glass and sapphire crystal glass in the absence of case detection instrument can be used to determine a simple way : a drop of water on the watch can be used on the glass surface , and then they stand up , the ball is not where the water was dispersed by the sapphire crystal Glass .
3, movement of fake and shoddy
Movement has produced the world's state of Switzerland , Japan, China and other countries. According to the movement of production and sales , from the brand with the tribute to determine the counterfeit watches .
(1) Where the imported Swiss watches , which uses the movement must be a Swiss production . Used in machine movement is found in Japan , China or other countries produce movement, the watch is fake and shoddy goods .
(2 ) the import of Japanese watches , which uses the movement must be produced in Japan . Found that for the Swiss movement , China or other countries produce the movement , the watch is fake and shoddy goods .
(3 ) domestic production of watch movements used in very complex , with Switzerland , Japan, and domestic movement, lies in the use of some shoddy movement pretends to watch sale , shoddy , Mongolia cheat consumers .
4 , to prevent counterfeiting and safeguard the interests of consumers
China's accession to WTO , the countries followed by the production of watches a lot of channels to enter the domestic market more competitive , should take effective measures to resist the invasion of fake and shoddy goods , reduce the risk of purchasing quality products . The following aspects must be strictly controlled to prevent counterfeit and shoddy goods, safeguard the interests of consumers .
(1 ) control supply channel and product quality of domestic production enterprises
(2 ) to strengthen the market supervision of product quality watches and clocks , regular testing or specialty store watch commercial sound products , announced the quality of sampling , and to inform the production and business units , failure of Kushiro on the watch limit or prohibit the sale of straighten out .
(3 ) receiving consumer complaints about the quality watches made of quality accreditation and the quality of notary .
Consumers to protect their own interests on the authenticity of the purchased goods with suspicion or mistrust of Quality Supervision, Inspection clocks can be detected to stop and issue inspection certificates.

The characteristics of silicone strap
We are not unfamiliar for the rubber strap . The silicone strap material as the new favorite , the movement is often diving in the watch . On the surface, this strap and rubber strap is very similar to the traditional , but it seems that differences between them.
Silicone is a huge family , divided into two major inorganic silica and organic silica ethnic lines . Inorganic silica is a highly active adsorption material , usually with sodium silicate and sulfuric acid reaction , and by aging, acid bulbs and a series of post-processing process prepared . Its main ingredient is silica , the structure like a sponge . Holes connected with each other to form a huge surface area of capillary absorption system to absorb and condense the water vapor equal to 40% of weight , so much for the desiccant . Although it is not used for the production of inorganic silicone bracelet , but the watch is often used in nursing - Just watch silica particles and water into the airtight container after a few hours out , then watch the water Will be lost.
Our daily use more organic silica gel , which is divided into silicone rubber, silicone resins and silicone oil , are a special synthetic rubber in rubber . Watch band material often used , it is organic silica gel in a small branch of the family , that is room temperature vulcanized silicone rubber silicone rubber (RTV).
Production of silicone rubber material is silica , methanol and hydrochloric acid , through a series of complex chemical processes can eventually be silicone rubber . This silicone rubber due to the lower molecular weight in liquid at room temperature , it is also known as "liquid silicone . " Mixes in liquid silicone crosslinker and platinum catalyst, then its into the model , after a period of curing reaction can be cured molding ( at room temperature the reaction can be , so as silicone rubber , can be slightly heated Improve the response speed) . And form the final product. Plus various additives can fill silicone materials have different specific gravity, hardness , strength , color and texture .
Pure silicone rubber than organic rubber has better resistance to high and low temperature performance. Traditional rubber in the sun can not shine on the space, will be frozen brittle , sealed during the sealing effect . As space was developed for silicon rubber material , the biggest feature is not afraid of high temperature and can withstand cold . Whether in the 300 ° C or -90 ° C in extreme environments , it may be poised to keep the chemical structure , without losing the original flexibility.
Compared with the natural rubber will not have the growth of bacteria . Low surface tension and its not easy to be soaked in sweat and rain deformation , and a strong water corrosion. Therefore, the silicone rubber product in the natural environment of the mission life of up to several decades.
Silicone rubber is not all-powerful , the tear resistance of rubber is lower in the category. Therefore, silicone strap with metal ring connections more vulnerable to external forces generated some small cracks . So use silicone bracelet , you need to pay attention to the connection strap with metal ring part , do not pull vigorously . In addition, the seasonal wipe clean soft cloth silicone strap, removal of hard, durable particles of dust , silicone to prevent scratches the surface of its small gap , but also effectively extends the strap life .
Silicone rubber with the general method to identify more complex by IR absorption peaks of the spectrum is different from the corresponding materials science to determine the species . But consumers can only be identified through the senses . Generally speaking, colorless and tasteless silicone products , when without a transparent color , if you add a different dye and can be black and color silicone gel . However, there will be some more or less rubber smell . Protein with a point of natural rubber itself, the taste of processed rubber with sulfur , will produce a special flavor . As for some people to judge through the flexibility that the silicone rubber touch softer than it is wrong. As ordinary rubber or resin material with different additives , the same can be achieved with much different silicone products flexibility.
