Retrograde Structure of Mechanical Movement

Watches Review Center Report: If the wrist is a face plate surface, then this function has a jump reverse face, certainly the most abundant expression, each to a certain moment, an instant bounce back to square one pointer to give the players more crumble space. Speaking of inverse function of the watch jump in recent years have produced many of the watch factory are all kinds of retrograde watches, mechanical models of the menu, seems to have formed a particular trend.

Inverse function of the origin of dance, watch the development in the medium term will have to show creativity watchmaker use (about 1905 or so), but used in the watch, the first appearing in 1997 by an independent system of Zurich, Switzerland watch Division PaulGerber published in the BASEL watchs show a jump function with inverse watch Retrograde. This innovative design, immediately aroused the attention of many people and cause heated discussions, the next few years, many of the watch factory in response to market demand started to make the inverse function of the watch jump.

Inverse jump on the market today are used in features to date, week, hours, minutes, seconds and other display structures, however, if the reverse jump a week, sometimes the user will miss such a wonderful picture, it most likely show the beauty of inverse jump should be one minute or 30 seconds against the jump function. 30 seconds to reverse jump, the one day mechanical structure of the watch must bear the 2,880 times the bounce back action, the movement mechanism of the inverse of the jump components are quite frequent and the stress is enormous, so the design must be very focused on stability and can withstand great stress and other serious topic, by the rapid development of modern CAD design, these problems can be solved.

The principle of reverse hop mainly by bouncing cam (a vortex-shaped metal reeds) and back to the trackwheel movement back and forth between bar and the reaction resulted in a rebound phenomenon of instantaneous gear, as mentioned earlier the number of rebound very frequent, stress concentration is too large, repeated movement against the jump component, the case of metal fatigue and failure than the other functions of the mechanical structure is more likely to occur. Because bouncing back trackwheel rod cam and the interaction requires a return to block the power of media as support, the source of the power structure in the reverse jump is often used as a medium rod spring file, but the file bar spring force as a larger role in the moment and often have long retreated strong enough force or power instability, and excessive bouncing cam will also be the stress concentration arising from wear and tear, deformation, then reverse time jump second part will appear error, and most cases occur mostly late spring (that is, slow seconds).

In view of this, Zurich watchmaker Paul Gerber came up to replace the spring lever springs, this problem has been resolved. Because the springs from the back addition to the supply stability, the situation is almost the aforementioned loss does not occur. Strictly speaking up against the hop is a violation of the principle of the innovative mechanical design, for which components will be more prone to easy wear and tear circumstances. Although many people happy every day because you can watch the pointer from the frequent movement, and prefer to watch against the jump, but before purchasing such a watch, a more general response to the mechanical structure easier to watch failure, has a clear understanding of the.

Variety Shaped Charm Watches

Watches Review Center Report: Watch as a large collection of fashion types also have their own style Variety. Early 19th century, there are many with insects, fruits and musical styles of watches across the globe, at the time so that fresh. Use your imagination to create the watch of the wealth, the biggest selling point is shaped watch. Show off with the four-dimensional multilateral reverie, creating space for the charm of strange, so shaped form to become a collector's treasure pet.

Wide variety of case

Famous Swiss brand Vacheron Constantin, not only has a long history of 250 years, and the design of the watch also has a variety of outstanding performance, so many of the brand watches always award-winning. Held in 1970, a watch design competition, a Vacheron Constantin pocket watch enamel, with its unique design won the "Innovation Award." This is an interesting watch, case cover sheet made of three separate enamel composition, respectively, black, green and blue, and every piece of enamel pieces can be turned on. When the case lid open later, we will find the dial in silver with a six pointer, labeled the three regions of the time, and each time zone are not the same color scale. Under the original design in appearance, Vacheron Constantin's watchmakers chose three separate quartz movement, quartz watch can be seen at the time of the trend, Vacheron Constantin brand new technology will also be applied to the works.

Two years later - June 23, 1972 in Paris, an asymmetric shape of the watch, relying on its unique and simple design won awards in one fell swoop, as the annals of Vacheron Constantin loaded in the classic works of one. Later, the watch into a single watch series, named "1972." In the newly published "1972" series of watches, we can still feel the avant-garde bold design concept - another case of parallel lines do not follow the established rules, instead of using a non-equilateral trapezoid shape.

Watch shapes and sizes

Things in nature always brings a lot of the design for the case material, whether it is a beautiful plant, or the ferocious animals, watch the hands of the designer can transform the unexpected results. Tissot's "Flower Rose" series will undoubtedly be noticed by many people, the most important reason is the flower-like design, this unique design of the watch on the petals will slowly start to the wearer. When the petals when the flower color will form a noble oval bud; by turning the crown surface, revealing the second layer, the absolute level of unique fashion trends to keep abreast of the people who put together an unusual style; completely Rotate the bezel off, the petals will be the third lap of luxury watch show in this paragraph exhaustive, Tissot's "flowers" to this fully rendered in front of the wearer. Similarly, the count from the designers to get inspired by the shape of a peach, after the design interpretation of the perceptual distortion of time personality.

Sometimes in our lives something inadvertently, due to the special design methods, can become a world famous watch. For example, the new Hermes "Kelly Clochette" watch is the "Kelly" padlock-shaped watch the mint, the design feature is the small child hidden in a locked leather bag, did not watch the traditional sense of the shape, but people thought that shaped the early form. In fact, "Kelly" padlock-shaped watch back in 1975, was created out of adhering to the Moroccan named after Princess Grace Kelly classic "Kelly" bag of features.

The combination of the watch dial and the drawer is what kind of feeling? Van Cleef & Arpels "Secret" watch a good answer to this question. Look closely, one side edge of the watch itself an intriguing little hidden drawers, the flowers along the crown pull, a natural mother of pearl surface immediately show, like a mysterious jewel box tells the secret of time!

Strange case design is also often the creation of an independent watch the direction of people like, such as Vianney Halter and Thomas Baumgartner, etc. to feel good will into the space age in the real world. The former case is designed to watch the whole circle is divided into four regions, located in the upper right is a hour, minute counter at the pointer, the pointer is located in the top left of the week shows a small round disk, the lower left of the display panel has two pointers of different lengths, respectively, month and leap year display pointer, and the last is the smallest circle is shown in the calendar, therefore, the traditional mode dial, this works by Vianney Halter's completely broken, but The calendar shows the complexity becomes very simple. The latter design watch in a closed case in a semi-circular orbit reveal, the number representing the hour and move it slowly in the meantime, like a shuttle between the spacecraft in space, makes memorable.

Watch knowledge: Jump Hour

New Watch Models Report: Today's hopping watch (Jump Hour) originated in the eighteenth century England George Graham, 1740 years he produced a series of Regulator Clock (three-pin line precision of clock time by astronomical standards), which has a small window to use with digital dial to display hour, has become the ancestor of today's jump watch. 1820 and 30 years, there have been hopping watch a short period of a brilliant and popular, but other times the 19th century, but had only maintain a small production of it; but the late nineteenth century, many people still jump to further develop the combined displayed when the pocket watch with jumping hours, heritage and developed the technology to display when jumping.

The Art Deco period of the last century, once again jump jump when the watch is displayed when the condenser re-registered watch making stage. Some watch giants such as Cartier and Audemars Piguet, watches began production of TH; but after the Great Depression and World War II. And the end of this a short recovery. In the 1970s, but also because the rise of a fully digital display hours, minutes, seconds, quartz digital watches, mechanical watches jump more diminished in the old.



Now refer to the watch jump, most people come to mind most often is probably the Gerald Genta brand name or Chronoswiss. But in fact, jump watchs should be attributed to a recent revival in 1989 launched two limited hopping watch: First, Breguet's Saltarello Souscription (50 only), the other is Patek Philippe's Tonneau 3969 (500 only).

The present altar watch, watch hopping Gerald Genta best known for the variety of the Delphis Chronoswiss Jumping Hour and design philosophy can be traced back to the source, in the process known around the world, specializes in the production of complex mechanical watches Vacheron Constantin Manufacture The Les Complications series Saltarello. Saltarello to figures in the 12 o'clock hour with a small window below the large fan with a retrograde minute display against the jump pointer to build there and most of this Chronoswiss Delphis Gerald Genta jump the basic elements of the watch.

Since then, the mechanical watch revival and rejuvenation market, competition results, a number of other new entrants to the brand, have jumped into the ranks of the time watch making. For example Dubey & Schaldenbrand and invited Vincent Calabrese of the Bell & Ross, have introduced a new jump watch, so like the one-eyed fans can not help but hi bounce from watch to. Perhaps, another wave of jump watch pandemic is brewing him? watch fans may wish to wait and see.

Details Construction and Working Principle of Mechanical Watch

Latest Watches News Report: About the early 16th century, sometimes in terms of invention, the first is to use gravity as a power source, this timepiece can only be placed in a fixed place, such as tall buildings, hanging on the wall clock is tied to the chain made with the iron hammer, and rotating around the wheel; later invented the use of the spring will make it run, which is now winding watches. This reduced in size when the count a lot, like a big egg, can be installed in the pocket, which is invented in Nuremberg, Germany Nuremberg Egg, all part of this watch is hand made, so costs time-consuming work, but only the watch each made everything in between. Until the 19th century, gradually developed to machine manufacturing, quality was able to control. Until now, watch the name of a very non-uniform structure, even in the same area, said there are many different laws or translation, and watch parts of the world also lacks uniform rules. Therefore, the Swiss movement manufacturer ETA to number the first number used to represent in order to watch parts industry when in with the correct options. However, the name of national brands had the same movement, but there are still differences in the structure, code will be different. Clock operation is the use of leverage, just like the swing back and forth like a repeat, the basic operation of the order of the center wheel by spring → → → the fourth round of the third round of the escape wheel → → → balance wheel cowboys, and then placed round of the reaction will be the messenger of a bounce in situ simple harmonic motion.

Barrel produced by the steel bar curl caused by the elastic force. In general, the barrel, also known as some cars (Barrel), by the Mainspring, Barrel Drum and the winding Barrel Cover the composition and use of the Ratchet Wheel drive to the center wheel and other gear, is watch the most important infrastructure work, like the human Stomach, as will the food come to eat into energy, this simple structure to facilitate the easy to use, so since ancient times change and small.

When you hear the watch "tick" "tick" sound like a metronome to keep swinging when the second hand on the dial along with the rhythm of rotation, so we immediately felt the continuous time flies. Cause of this rhythm is due to sound like a balance wheel by the force of reaction to the messenger Lever generated voice. Balance wheel system is composed of alloys and to Hairspring caused by reaction to promote the gem Impulse Jewel Pin bounced back Lever, a perfect balance wheel is usually 225 degrees to 270 degrees swing keep swinging, so that time is always going.

Watch the main structure, in addition to the previously mentioned spring and balance wheel in the middle of the main gear is also a time to run to the main part, they are like human blood continue to receive power transmitted from barrel. The main gear includes: (1) Center Wheel or 2nd Wheel; (2) 3rd Wheel; (3) 4th Wheel; (4) Escape Wheel, were responsible for these gears from time to time, minutes, seconds, and so when the rhythm of the transmission function. The beginning of all the power to send forces from the spring to tighten the center wheel, third round, fourth round, escape wheel, clamp, and then to the balance wheel, then wheel it back before the reaction to the location of cowboys, so As a result, the whole process can be run again and again.

Normally when we see the watch, minutes and seconds indicators show how they are allocated through the gears it? When the winding to provide power to the center wheel, the center will be 60 minutes a round circle of rotation speed, to the third round of the situation when you started to have transmission, transfer to the fourth round of the 60 seconds is based on a rate of 1 lap turn. So the minute hand through the center of the display is produced by the axis of wheels, second hand display is produced by the axis of the fourth round, as the clock display, it is linked by the board in the minute hand on the wheel when the wheel to generate The. Most people will find some of the watch small second hand at 6 o'clock or 9 o'clock position, which is in accordance with the position of the fourth round to decide. Also the design of a large second hand is in the fourth round of the installation of a gear system, so that the location of the second hand to transform. Watch the players love, after some detailed explanations, added a lot of your skill is?

watch the one-way and bi-directional automatic winding mechanism


Fashion Watch Trend Report: 1931, published a ROLEX Perpetual Rolex watch, the thickness of 7.5mm, it is the world's first automated disc can watch 360-degree rotation, but only one-way on the chain.

Automatic course of development
1770, Abranham-Louis Perrelet created a self-winding watch, shortly after Abraham-Louis Breguet was modified but not widely used, so self-winding watch has not yet born. Later, to the early 1920s, John Harwood has developed the first self-winding watch and patented, but then Harhood self-winding watch produced is still a semi-automatic watch hit Tuo; and the so-called hit Tuo-style, that is, it is not able to complete 360-degree horizontal rotation, and we are now using a self-winding mechanism is still different. ROLEX in 1931 until the introduction of a water feature with self-winding automatic watch before I really make a 360 degree rotating disk, while While this is called "perpetual rotor " The movement is widely equipped in three Friday's Rolex bubble back into the watch, but it is still only one-way on the chain, the chain of two-way R & D to come out to ten years before, which makes automatic chain can be more efficient. Self-winding mechanism for the subsequent continuous improvement, to the movement of the 1950s began to do light, some watchmakers began to use gold or platinum as an automatic plate material, the higher the weight of the feature makes the watch to become thinner and because can help the performance of the chain, which is self-winding several important milestones in the development.



Automatic structural components of the name: 1. Automatic plate, 2. Automatic rotation, 3. And 4. Automatically some wheels (both coaxial), 5. And 6. Auto two fan wheels (two coaxial), 7 . Automatic wheel San Francisco, 8. automatically quadruple round, 9. Large vehicles (ie large drum), 10. barrel.

Bi-directional automatic winding mechanism
The picture above shows the use of two double two-way on the back wheel of the automatic winding mechanism for refining. Two-way on the chain is a more complex structure, but in fact the principle of transmission are interlinked with one-way, we can clearly see the direction of automatic chain gear, when the automatic plate 1. To rotate, this time with coaxial Automatic round 2. will rotate in conjunction with the direction of homeopathy, and its phase two double bite back wheel 3.4. and 5.6. idling through the rotation mechanism to promote and will triple their round 7. push ahead, and then transfer to four fan wheel 8., the following four rounds of the small fan gear again and Large car bite, the winding on the chain, which is a complete program. In fact, two-way on the chain have a basic concept, it must have two sets of gear with each other for a cover of the rotation in order to produce two sets of gear turns forward on the chain effect. In fact, each of the two gears, a brand of how to turn on the chain of different designs, a similar way clutch, but also a spin in turn one way forward, even the non-return devices also vary by design.

Photo: 1926 by HARHOOD patent, the first automatic winding watch, the use of semi-automatic collision Tuo
(That is not 360 degree rotation) one-way on the chain.

Self-winding mechanism for one-way
The so-called one-way and two-way on the chain difference is whether the automatic plate has a clockwise and counterclockwise rotation of gear to promote the chain, if the chain is only one direction, another direction of rotation, the gear must be slippage, that is, on the one-way chain. Automatic name suggests is a one-way automatic panel can be only one direction on the chain, that is, some rounds from automatic transmission to Tai continuous reel, but the other direction can not be on the chain, so to be idle gear, or through a clutch gear as an intermediary, to sever relations with all automatic transmission between the drive wheel, which is a simple one-way on the chain principle, and we often say that the efficiency of one-way Automatic limited, that is, half the time because of the automatic disk are in fact In the idling of the reason.

Photo: Left to AUDEMARS PIGUET Automatic plate movement, right movement PATEK PHILIPPE was automatically set.

The shape and design of automatic plate
Today we can see a lot of automatic watch in the automatic drive to do different designs, we are curious whether the shape will have different impact on the chain efficiency? In fact, the shape of the automatic plate is not much impact on the chain, but added that with the weight of the material the way, many brands like to use 21K gold plate material to create the automatic block, which is helpful on the chain efficiency, but more emphasis on aesthetics, or, for the thin sheet, the entire precious metals to create an automatic disk but will become a burden, so they are mostly produced by automatic plate outer edge of the practice of a noble metal to improve the efficiency of the chain.

Automatic plate bearing the type
In addition, automatic disk position in the movement of the central axis, in order to reduce the rotation of 360 degrees and may create friction, must have a device called a bearing axis and automatic disk as undertake media, the media can help Automatic disk spin on the refining effect, and therefore can have different designs, it is left above the design of ruby bearings, on both sides of the axis of the ruby; To the right was the design of ball bearings (both sides of the axis Splitting two round ball), but there are five or seven ball bearing design, but also the design of ceramic materials, and many brands like to use this advanced design.

Detail of Swiss Chronograph Movement

Watches Review Center Report: Play watch who can not always sweep plus the date, it is only practical models only. Entry-level multi-function, the most important function of Sun Moon Star and timing, the former quiet, but more the way of several display, skill, aesthetics and adjust the presentation of the way; the latter Chongwu, between dynamic and static switch, the time span of the calculation, more than a lot of fun. From the pocket watch era, time shall become an important feature to have gaps of time constraints, such as the modern watch times, people prefer to the actual calculation of a function of time. Time, has become the most important functions of the watch.

Part I: Famous chronograph movement plant

A, Lemania

A long time ago, the Swiss watch industry will have a ASUAG and SSIH (SWATCH, the predecessor of what is now) the two major groups exist. There are three core chronograph movement ASUAG factories were Landeron, Venus, Valjoux company. As ASUAG competitors SSIH, there is a magic weapon to contend with, this is the famous LEMANIA company. In 1884, a company called Roriento established. This is LEMANIA predecessor, from 1912 onwards, it has started processing the movement for the OMEGA. In 1932, it became a member of SSHI Group (this group includes the Omega was the core TISSOT, RADO, LONGINES). After not long, it was spun off from the SSIH group, but continue to produce SSIH use of the brand within the time products, in particular, and OMEGA are very closely related, once mighty. Quartz wave until the arrival of 1970, the company faces bankruptcy danger of disintegration. In 1981 BREGUET , the company acquired investment LEMANIA, it became a member of the Group BREGUET. Name changed to the new LEMANIA company. In 1999, as the parent of the existence of BREGUET, by SWATCH Group acquired, LEMANIA another dramatic and OMEGA, LONGINES reunion of the old partners, the Swiss watch manufacturing industry one of the beam column arrived.

1. Lemania 15TL
1920s, began producing the famous 15TL, it is almost time LEMANIA developed the first successful movement. While this movement has had the core of the mature technology of modern time. First used in hand-rolled pocket watch. Los Angeles Olympics in 1932 While this product to use, after the watch has used it. Looking back, not only original but also very famous. Note that it is column-wheel with 7 tooth structure, was already quite advanced and sophisticated. Normal small second hand at 6 o'clock, chronograph minute hand and the position of plate 12.

2. Lemania 27CH
Lemania 27CH is LEMANI and OMEGA co-crystallization. Standard movement published in 1942 by the Jaques Reymond and Lemania Omega watchmakers Albert Piguet joint development, model 27 CHRO C12. Diameter 27MM. Later, in 1946, OMEGA to revise it to 321 for SPEEDMASTER assembly. Its column wheel, with 8 teeth. More sophisticated easy to use. It's a small second hand at 9 o'clock position, time minute hand at 3 o'clock position. Variant of the famous models have a more famous manufacturers in the use, it is Prince Philip. After Philip modifications and upgrades, Lemania2310 (that is 27CH) has become the main core member PATEK time. Applied to the modern REF. 5070,3970 and other models, praised by experts and sought after players.

3.1270
This is LEMAINIA in 27CH and cam-style over the middle of 1872 products manufactured from the 1960s. Cam works, permanent second hand at 9 o'clock, minute counter at 3 o'clock position, the diameter is 27MM, note that these are the manufacturing costs are: 27CH> 1270> 1872

4.1872
1872 is the famous OMEGA 860 series, diameter 27MM, which is LEMANIA OMEGA in 1972 and works jointly developed with the previous biggest difference is time the Centre has adopted the eccentric timing structure, Y-shaped splint was changed to a more swatch simple form. Production and assembly easier, and costs significantly reduced. Small seconds at 9 o'clock position, time minute hand at 3 o'clock, chronograph hours at 6 o'clock position. While this movement is simple and durable, the completion of a demanding test, once equipped with the OMEGA SPEEDMASTER on the moon.

5.1340
1340 1040 OMEGA automatic timing is a 1970s production, this is the first automatic timing LEMANIA core. Cam-type timing center, two points are different from the past: power transmission mode is walking arm-style, traditional slip into gear to be canceled. Another time the second hand and minute hand have adopted the Central time configuration. 1350 was a more mature modern BREGUET, bao and other brands used.

6.5100

The 5100 is more mature then the automatic timing core, this is called the OMEGA CAL.1045. Beginning in 1974, manufacturing, practical 24-hour display at 12 o'clock position is designed, While this movement is still being produced until now, but NATO used to be a large number of military form of production. TUTIMA and SINN are used. ETA7750 carries it to someone and comparison between different,

Second, Valjoux

Valjoux timing is not the most famous pin factory, has no doubt. The SWATCH-ETA now a part of the world's largest manufacturer of timing factory movement has a face-lift for the general life-long service. Valjoux in French Vallee de Joux Valley, the meaning of Ru. 1901, Raymond Brothers was founded in the Ru-valley situation of this in the future of the company, began when the company is named after two brothers, but how long, Val de Joux become a brand name, Raymond family before being acquired has been in operation ETA the company, you not seen the bottom of the balance wheel of the great "R" in the tag? It was Raymond's first letter. ROLEX DAYTONA someone found the famous "R" flower standard, that is the core self ROLEX, it is a very subjective idea of it. In the 80 years after the wave of quartz, ETA acquisition Valjoux, Valjoux time to produce the core of this historical giant, declared bankruptcy. 

1. CAL.22

In 1914, the famous core CAL.22 core advent of time, the company has laid a milestone for the Valjoux. CAL.22 a 9 tooth structure column wheel chronograph, very sophisticated. Was no seismic device, power transmission mode is walking arm-style, slip into gear with the traditional format. Start and stop with the spring bar, was screws. Diameter: 31.58mm, small seconds at 9 o'clock position, chronograph minute hand at 3 o'clock position. CAL.22 later time with a 12-hour drive to become CAL.71. Another 22 type has a lower grade of deformation, the GHT format, note that it's time for the 6 column-wheel teeth, less than the traditional 22 advanced.

2. CAL.23

1916, experienced a three times improvement CAL.22, introduced CAL.23 type, using the same column wheel chronograph 9 tooth structure, no seismic device, power transmission mode is walking arm-style, slip into gear with the traditional format . Start and stop with the spring bar, was screws. CAL.23 much better technically, its diameter is reduced to: 29.32mm. This type of laying a late 23's CAL.72 the advent of the most outstanding.

3. CAL72

1946, CAL.72 come out. This is a perfect time in the history of the movement. From the structure and process, and impeccable. While retaining the traditional 9-tooth sprocket and walking arm-style, slip into gear and other formats, the new joined-hour drive time, plus new designs of English Gabriel recorded a shock , sweep, including rivers and lakes .... including a large number of outstanding ROLEX brand are used. Diameter of 29.32mm, second hand: 9 o'clock position, time minute hand: 3 o'clock, chronograph hours: 6 o'clock. This type after 77 and 92, power transmission to shake type, inexpensive model of industrialization, has begun to show. In 1974, While this time the famous classic has been declared discontinued.

4. CAL.7730

In 1967, CAL.7730 come out. It abolished the traditional column wheel as the time to switch cam control center, from the structurally more simple and easier maintenance. Its diameter is 31.58mm, the small second hand: 9 o'clock, minute counter at 3 o'clock in the position. Switzerland in 1978 and 7730 to stop production, but mimics the structure of the Poljot 3133 has been in production. In 1969, more than 7730 of the 7733 advent of simple, mass production of the timing core, flooding the market. Cheap but is it poor quality? History of its own conclusions, people like, or traditional column wheel 9 tooth beauty and Y-shaped clip version of the harmony. A version called the 7734 date display, a 12-hour accumulated total is 7736. HMT 7733 the company bought the manufacturing and import and export license, is now being produced in India.

5. CAL.7750

July 1, 1974, modified 7750 by the 7740 advent of automatic timing. He has many variants, such as: 7751 (plus a perpetual calendar and moon phase) 7760 (7750 manual version) 7761 (7751 manual version) 7758 (plus the phase of the moon) 7765 (manual, but different, and 7760). The largest output of modern Switzerland, the most frequently used timing core. Its diameter is 30mm, small seconds at 9 o'clock, minute counter at 6 o'clock in the location, hours of drive time in the 12 o'clock position, it uses cam timing, power transmission for the shake-style, not slip into gear. Is already the most modern and compact design. Not the traditional concept.

Third, Venus

Venus is a beautiful name, as the chronograph movement, Valjoux with it and give a high evaluation is outside of the manufacturers. Venus was founded in 1924 by Schmitz, p & jb berret Founded by three. 20-50 years of his work in the market in a very good reputation. In 1969, Venus bleak ending, failure to close.

1.150

Venus 1950 150 core to begin production of the main intermediate models. Column wheel with 7 tooth structure, timing, transmission method for the walking arm-type, the use of slip into gear. There are two small cap 150 can be calculated minute span, there are three small cap can be calculated by a 152-hour span. Venus 150 and 175, the same principles and structure, just different sizes. 150 Diameter: 29.32mm. 175 Diameter: 31.58mm. It's a small second hand at 9 o'clock, minute counter at 3 o'clock position.

2.178

This is Venus the most outstanding products, made since 1950. Breitling is the famous large-scale use. Time center column wheel with 7 tooth structure, transmission methods for the walking arm-type, the use of slip into gear, 175 is a two time offer. There was a three time disk 178. Its diameter is large than 150 2.26mm. Small second hand: 9 o'clock position, minutes counter at 3 o'clock, hour counter at 6 o'clock position.

3.196

This is a popular 40-50 years of small time core. LEONIDAS supplied by the same column wheel with 7 tooth structure was walking arm-type transmission mode, using slip into gear, its diameter is 23.7mm, suiwatch for small watch, the normal small second hand at 6 o'clock, attention, It can only calculate the activities within 60 seconds, no minutes of class time settings.

4.188 170

188 is the first production of the cheap version of Venus, the working principle of a cam-type, but to stick with walking arm-and slip into gear. Small seconds at 9 o'clock Chronograph minute hand at 3 o'clock position. The 200 was also changed from 188.CAL.170 began to be produced from 1945, and 188 together, is a cheap mass-produced version of Venus, although it uses a column wheel structure, but the momentum has changed to low-cost means of communication rocking style. This, too simplistic an experimental trends it. Small second hand is rather special, at 6 o'clock, minute counter at 12 o'clock.

Fourth, Landeron

Landeron is a manufacturer of low-cost core brands. Something big and stupid. Moreover, it has a considerable negative impact on yield and, not to mention it and then Bovet Freres & Co SA is also inextricably linked.

48 (old type) is a representative, then at least make Landeron still very formal thing. Using low-cost cam timing, which is Landeron first cam structure. It is to stick with walking arm-and slip into gear. Want to know is that it's time now operate in different ways, is starting on the button, the button is to stop & reset. From 48 (new), the reset hammer is made of a simple graphic design. This is to easy to produce, they longed to be only one part to complete all the work. , On the button to take a new start & stop function, the button changes to bear only reset.

51 era-type can be seen is how the time step by step into the low-cost core. Withstand the early shift round the body the body and the cam also dedicated a single production transition to the post once the pressure built altogether on it, the convenience was a lot. However, the test of time, proving once again that age only with the heart-made quality, can experience the old and intact. Then later some terrible version of the operating contacts are cheap wire rod replacement, such as CAL.77. This should be self-defeating outcome of these designer bar the door.
