Do you really know your watch?

As a customer who needs to customize the watch, you probably don't have to know every part of the watch you need, but you should know it at least before you customize it.
Composition of watches
A, machine core (domestic or imported)
B. Case (including table cover and bottom cover)
C, band (metal or leather)
D, dial (copper, aluminum, paper)
E, rear cover (stainless steel)
F, watch, watch, etc
(A) the core
The core is the most important part of the watch. It is the "heart" of the watch. The quality of the watch determines the quality of the watch and the quality of the watch, which is crucial to the quality of the watch. Japan's original western iron city machinery self-motivation core, its product defective rate is only 5 ‰, the daily error is plus or minus 15 seconds: the domestic automatic mechanical core, its product unqualified rate is 7 ‰, the daily error is plus or minus 30 seconds. The quartz core of west iron city is the most commonly used machine core of many watch manufacturers at home and abroad. The unqualified product is only 3 ‰, and the monthly error is plus or minus 30 seconds. The core of west iron city, in many brands of the core, it wins the international and domestic market with the moving characteristics and excellent accuracy. In recent years, the quality of domestic mechanical core has been improving and its quality is stable.
(B) the case of surface shell of domestic market is currently used in alloy shell, copper shell, steel shell, tungsten steel shell and so on.
1. Alloy shell: generally speaking, the processing technology is simple, the production cycle is short, the production is large, the price is low, and the development is relatively fast in recent years. However, due to its water resistance, abrasion resistance, corrosion resistance and so on, it is seldom used in large-scale celebration activities, and generally used in promotions such as beer and beverage. Belong to medium, low grade watch.
2. Copper shell: copper shell has the advantages of easy processing, beautiful appearance, good waterproof performance, surface abrasion resistance and corrosion resistance. Many manufacturers are mostly adopted. Its modest price is also an advantage. Belonging to the high and middle class watch.
3. Steel shell: generally speaking, the processing is more complicated, the output is small, the price is higher, its performance is higher than the alloy shell and the copper shell, generally used in the high-end electronic watch and mechanical or mechanical automatic watch. It belongs to an upscale watch.
4. Tungsten steel shell: it is difficult to process, not easy to wear, and it is equipped with sapphire watch, Japanese machine core and tungsten steel strap. This watch is usually a high-end electronic watch.
(C) band
The selection of the strap should generally match the surface of the case, choosing what kind of surface to choose from. Except for one case, the surface of any material can match the leather strap, and the effect is ideal.
(D) dial
The dial material is usually made of copper, aluminum, paper and so on. For a watch, the design of the dial is also very important, in our industry, called the dial "plate face", as if a person's face is just as important. Also a watch case with different patterns and textures can achieve different effects.
(E) rear cover
The back cover of the watch is fixed in the core, dust proof, water - proof, etc. It is made of stainless steel. The back can corrode the text and design, and it has three assembly modes.
1. Press the cover to work closely with the case (on time) (less waterproof)
Screw and tighten the cover and rear cover.
3. The rose bottom case and the rear cover are fixed with rose, generally seen in the square case (waterproof).
(F) the watch needle and watch are the important parts of the display time. The general watch should have three hands, minute and second hand, with exceptional circumstances. For example, ultra-thin watch, usually only hand and minute hand, the second hand is optional.
The table is an important part of adjusting the hour (time), date (calendar), mostly manual. Generally, copper plating or stainless steel is used.
The band is divided into: ceramic belt, metal belt (tungsten titanium alloy belt, solid steel belt, solid copper belt, solid powder metallurgy steel belt, steel strip, wire braid etc.), belt, nylon braid etc. The ceramic band has the characteristics of not easy to wear, not allergic, beautiful and so on.
 
Each watch is a combination of several hundred or more parts, and we often need to design it according to its functional requirements.
