The one constant of human need that everyone recognized units of measurement and endless , and finally , select a basic unit in seconds . Seconds back to the Sumerian culture to use as early as 4000 years ago, the Sumerians had begun using six decimal count system . Nature of the timing unit is the Earth's speed of rotation of the week, time spent is divided into 24 hours , an hour into 60 minutes , 60 seconds per minute , a day there are 1440 minutes , which is 86400 seconds . Now the world's use of official time , the so-called standard time , in Paris, France by the Board authorized the calculation of international time , all clocks are to it as the standard . In fact , emerging from the watch the day , how to form " quasi- go "- as accurately as possible reflect the time clock has become a basic direction for the industry .
The original watch is not accurate , one hour one day difference is quite normal things , but today, a high quality mechanical watch every day the error is between 2-5 seconds . Excellent quartz watch is a month to appear the same error , as to the accuracy of cesium clock higher , 30 years before a second error .
Watch how the accuracy of their good or bad the quality is very important , and watches in addition to the quality of materials and external decoration , the key depends on whether it has a heart design , fine workmanship, perfect mosaic of heart - movement . An authentic name factory watch - such as a price of up to 500,000 yuan of the complex function watch , with a price of 50-80 yuan only ordinary mechanical watch what the difference? Can be said that the difference between them like a fisherman's hut and the magnificent castle.
An ordinary watch about 90 to 120 parts, are manufactured and mounted by the machine can display hours and minutes , some seconds or even weeks, the date can be displayed . Those prices range from several hundred dollars to several thousand dollars, multi-function watch , the most available time watch . Watch the operation of built-in two separate parts , a set of display time , another set of Zeyi measure the length of the measurement from one moment to another moment experienced by the middle of the time . Watch in about 200 blocks of parts, operating independently , and to promote the hours, minutes , seconds of unrelated parts . The most famous , the most precious "complex menu " , the internal structure of precision , there are parts about 1400 .
Each watch in the heart of the complex are five components
Drive parts: gossamer winding , is a thin spiral steel , length is 20-60 cm in thickness can only be from 00.5 to 0.20 mm , curled hidden in a gear chain plate.
Communication parts: gear drive system , a group of gears , each of which are installed in the shaft , large or small, rod , gear tooth is connected to transmit power to the escapement device and display the time portion.
Accept the part : the escapement . It created what then about the pulse of the power distribution to the balance wheel , balance wheel regularly to vibration .
Some adjustment : the balance wheel . It swings back and forth rhythmically , the average division of a period of time , adjusting gear drive system of rotation , to ensure the normal operation of watches .
Show parts: the time display . Including the dial and pointer .
The five parts of the operation is good or not depends on whether the parts were precision manufacturing , assembly effort must be absolutely accurate , must not have the slightest deviation . The least bit of difference , huge mistakes. Slight flaw can undermine the accuracy of the watch and even called the whole watch just stop working .
"Multi-functional watches " The movement is the watch design and manufacturing technology and sophisticated technology for superb the only show outside of time , it is focused on a variety of other functions . Such as moon phases and seasonal display and can set the hour , every 15 minutes the alarm report for a calendar , etc. . The structure of this form dense , its design is like a house , a cascading style . The bottom is the dungeon , is the time device , display hours, minutes , seconds; second is the newspaper to play spring device design sophisticated models can be hourly, every quarter of an hour , every five minutes the newspaper , even after each quarter of an hour -by- Points timekeeping . Movement from the 1400 to 1800 parts, individual one-thousandth of millimeter size have been the top chefs in each part of the cutting, polishing , and Zhuo -made .
On technology , science and technology and manual skills , the world is only a few European equipment Zhuzhong clock factory set conditions , can produce a few watches . Looking at the industry today , know how to make these " complicated menu " of the craftsman . Fewer than 100 . The skilled craftsmen create a tabulation of such movement, generally take six to twelve months .
Tourbillon is the most sophisticated manufacturing process watch , one of the most innovative devices , is one of the most accurate masterpieces . Collection of escapement device , the center part of the hidden part of the regulation . Known as the " watchmaker King "and" King Queen watchmaker "the reputation of Swiss Wembley cover , designed in the 1791 tourbillon . 80 years of the 20th century , complicated watches and features a mixture of tourbillion watch , so to add a feature . Naturally, only very expensive watches will be fitted with it.
" transparent watch " may be said to watch the peak of the design , the watch panels and plywood are not sealed -style , looks as if all parts of the hair only by very finely linked , how storage and transportation device rotation , pendulum How wheel vibration, and how the escapement bar before and after the swing , etc. , are clear . This wonderful design , people seemed to see the pulse of life within , and awareness to a world of secrets , not help Jiaoren amazing.
