At before, we shared something about what kind of materials can be used to produce different watch parts. But we just mentioned an approximate part of a watch, like watch case, watch hands, dial, watch band etc. In fact, there are more detailed parts which are important for a watch.
For example, watch case factory need many other factories in his supply chain to help finish the whole watch case, it mainly includes below factories:
1. Watch case mold factory, help opening mold for the watch case
2. Glass factory: help producing watch glass
3. Crown factory: help producing crown in different shape
4. Waterproof ring factory: help producing waterproof rings for glass, back case, crown
5. Ceramic products factory: help producing ceramic bezel for watch bezels
6. Laser/engrave factory: help engraving numbers or markers on watch bezel, doing logo on back case or watch case
7. Oil filling factory: help filling color oil or luminous oil on watch bezel or crown
8. Back case factory: help producing the watch back case
9. Movement holder factory: help producing movement holders for watch movements
10. Slingshot factory: help producing leaf spring or spring line for rotatable watch bezel
In the same way, other accessories (dial, needle, strap, buckle) are also required for many other factories to help complete the production of a whole accessory. The production of a complete watch may need the cooperation of over 20 factories. Because of that, there may be only a few brands in all watch brands in the world that produce all of their own accessories independently.
