China is the most important watch base in the world. There are countless large and small watch manufacturers scattered in the Pearl River Delta. These upper, middle, and downstream watch manufacturers form a huge and delicate watch industry chain.
The case is the main part of the watch. If the movement is the core of a watch, then the case is the main body of a watch. The structure and appearance of the case and the level of craftsmanship directly reflect the design of the watch.
The case of the watch is divided by material, mainly zinc alloy case, copper case, steel case and titanium case. The general processing flow of various metal cases is not too different.
The assembly accessories needed for the finished watch case are: crown tube, glass, back cover, bezel, decorative small miscellaneous parts and screws, movement holder, seal ring, etc.
The raw material for the production and processing of watch case is the watch blank, and the main process steps are: turning, milling, drilling, grinding, etc.
The main processing flow of the metal case is as follows:
The watch blank processing-turning, drilling and milling processing-surface processing (polishing / SATIN / sand blasting, etc.)-surface treatment (plating, etching, etc.)-case parts assembly
Of course, this is just a general sharing of simple processing procedures, and there are still many details that are not mentioned. To make a watch case requires not only the meticulous processing of each department process and the cooperation of each process, but also skilled technicians, especially in the polishing process, the surface effect depends on the master.
