The processes of make a watch case


The case usually refers to watch the body (header) shell parts, its role is to protect the internal components of tolerance and watch (movement, dial, hands, etc.) is closely connected with the case parts are: table mirror, bottom cover, crown, button etc..


The case is like the human body, in addition to its direct care watch "guts", at the same time largely determines the performance index, such as: watch waterproof, dustproof performance, antimagnetic performance and seismic performance, in addition, the case also controls the watch body appearance.

In addition, the watch also controls the appearance of the watch body.


Case classification is usually based on the material division, the more common are: stainless steel case, tungsten steel case, ceramic case, titanium alloy watchcase, watchcase, watchcase, copper aluminum zinc alloy case, plastic case; in addition, the less common and wooden watchcase, watchcase, watchcase, iron fiber, gold or silver. K gold watch case.


According to the case if style classification, there is a round case, square case, barrel shaped watchcase, oval shaped case......


Making process

Embryo (watch blank): a coarse embryo made before the watch case. The surface of the embryo is treated by surface treatment, such as grinding, electroplating, diamond setting and so on. It can be assembled into a watch case.


Embryo is mainly divided into: titanium embryo, tungsten steel embryo, ceramic embryo, zinc alloy embryo, copper embryo, aluminum embryo, stainless steel embryo,  plastic embryo. The titanium embryo, tungsten steel embryo,  ceramic embryo belongs to high-grade embryo.


The first step: oil machine (Rough bottom, ear foot)

The second step: NC machine (fine car bottom, ear foot)

The fifth step: grinding (surface polishing)


The sixth step: picking, packaging


Polishing material

Case material: yellow wax, polishing wax, wax purple, line wheel, nylon wheel, belt wheel, grass, sponge wheel, wind wheel and so on. After grinding and polishing, the case surface is very bright.
