The composition consisting watch watches 
A, movement (Origin: minutes of domestic or imported, the type can be divided into quartz, mechanical and LCD electronic)
B, case (including table Mongolia, bottom)
C, scrap (metal or leather)
D, dial (copper, aluminum, paper)
E, the back cover (stainless steel)
F, hands, crown, etc.
(A) movement is the most important part of the watch movement, is watching the "heart", its quality determines the quality of the watch is good or bad, the choice of quality of movement, for the product quality is essential. Japanese original Citizen quartz movement, and its product failure rate was 5, May error 15 seconds: Domestic quartz movement, and its product failure rate of 7, date error is 30 seconds. Citizen quartz movement watches are many domestic and foreign manufacturers currently the most commonly used movement, product failure rate was only 3, March error 30 seconds. Citizen movement, movement in many brands, which by touching features and superior accuracy to win the praise of international and domestic markets. In recent years, China-made mechanical automatic movement is improving the quality of its products. The quality is stable.
(B) Case domestic market to use more alloy shell, copper shell, steel, tungsten steel and so on. An alloy shell: In general machining process is easy, short production cycle, production, low prices, relatively rapid development in recent years. However, due to its water resistance, wear resistance, corrosion resistance and other aspects of more than a lack of large-scale celebrations rarely utilized, and more generally use in such as beer, beverage and other aspects of promotion in. Owned by the low-grade class watches. 2, copper shells: copper shell has easy processing, beautiful, good waterproof properties, surface abrasion and corrosion resistance and other aspects of the advantages. Many manufacturers mostly use. Moderate its price is also its advantage. Are High, mid-range class watches. 3, steel: In conventional machining complex, small production, high prices, and its performance is higher than shell and copper alloy shell, generally used for high-end electronic or mechanical automatic watches and mechanical watches. Belong to the high-end watches. 4, tungsten steel: the difficulty of processing large, easy to wear, and a sapphire Mongolia, Japan movement, tungsten steel strap. This table is typically high-end electronic watches.
(C) Band selection should generally be matched with the case, the choice of what kind of material the case what kind of strap on the election. There is a situation can be the exception, and that is the case any material can match the leather strap. The effect is more ideal.
D) Dial material generally uses copper, aluminum, paper and so on. For a watch, the dial design is very important in our industry, said the dial to "fish face", as if a person's face is just as important. Similarly a case, coupled with different patterns and textures of the dial, you can achieve different effects.
(E) the role of the back cover of the watch cover is fixed movement, dust, water and so on. More use of stainless steel. Back to text and etched patterns, it is usually the case, there are three assembly methods. 1, according to the cover and the case directly to work closely with (time) (the water is poor) 2, screw cap cover both the case and the rib and tightening (waterproof and strong) 3, the end of the case and cover with Rose Rose fixed, usually more common in the square case (waterproof and strong)
(F) hands and crown
Show time is an important component of the hands. The general should watch the hour, minute and second hand three, except in special circumstances. Such as ultra-thin watches, generally only hour and minute hands, according to movement of the second hand case dispensable. The crown is adjusted clockwise (Time), date (calendar) of the principal parts, mostly manual. More commonly used copper plating plus or stainless steel. Of course, a good watch is customized in every detail, the best materials are used to reach the best quality parts on each

History of watches

Human exactly when to start, with the concept of "time"?

   The earliest human ancestor to know from the dismal days of the passage of time tomorrow. About six thousand years ago, the "clock" first on the stage of human history: a sundial in the kingdom of Babylon was created. Ancient sundial, time based on the sun shadow master changes the length and orientation. Dating back four thousand years ago, the clepsydra come out, so that people can hear the time of day or night. And watch the emergence of the middle of the thirteenth century is something in the future.
   After one hundred twenty-seven o ago in northern Italy and southern Germany in the vicinity of the early mechanical clock appeared to bob for power, that comes with the bell ringing every hour, automatic timekeeping. 1336, first public clocks were installed in a church in Milan, in the next half century, the clock spread to European countries, France, Germany, Italy, the church bell tower has been built.
   Soon, clockwork technology invented, greatly reduced the volume of the clock. One hundred fifty-one O, the German locksmith for the first time the system out-of-pocket. That year, the production seems to be limited to watching locksmith sideline until later on increasingly demanding precision clocks, watches skill and sophistication. It appears a professional watchmaker.

   Eighteen O six years, Napoleon's wife, Empress J. Dove to lute a watch specially designed for the princess, is the earliest known record of the watch. This is just an emphasis on decoration, is made bracelet-like watches. At that time, a man of the world where the line is as a phoenix identity, status symbol watch, watches were seen as women's accessories.
   1885, a large number of German naval custom watches, watches practicality sure to get the world to Swiss watchmaker, gradually increasing in popularity.
   Beginning of this century. ROLEX (Rolex), the predecessor --WILSDORF & DAVIS launched silver ladies and gentlemen table, a big success, led the research and development of various manufacturers compete watches. Then on to the world-famous Swiss watch skill in watch making has also set the stage, ROLEX in 1926 on the development of a completely waterproof watch "ROLEX OYSTER", 1931 and will be the first self-winding watch "OYSTER PERPETUAL" to the market. LONGINES (Longines) company to be outdone, the development of precision clocks and American Airlines flight home Lindbergh fly across the Atlantic together, became famous. 1929, launched watches stopwatch function "CHRONOGRAPH", the following year and on this basis to develop a flight with a precision watch "CHRONOMETER".
   The late sixties, mechanical watches has opened a new page in history: in 1969, the Japanese Seiko watch company developed the world's first quartz digital watches, day error decreased to less than 0.2 seconds. 1972, the United States, Hamilton invented the numerical display watches, motor and gear disappeared from the watch.
   Watch the manufacturing of innovative technologies emerging, but did not come to an end mechanical watches, although greatly reduced production, manufacturing techniques have been saved. In particular, the Swiss watch manufacturer, quartz watches champion today, still a soft spot for mechanical watches, adhere to the production of high-end mechanical watches, and an endless stream of exports to the rest of the world.
