Can the domestic 7750 movement and Swiss 7750 accessories be interchanged?

Domestic 7750 movement and Swiss 7750 accessories are interchangeable. It is easy to slip where the domestic 7750 is wound. If the parts are universal, it should be much better to have ETA on the wound parts.

There are watch factories in Europe that use 7750 movements made in China, and those in Shanghai, Dandong and Tianjin are all good. Those that have been used for ten years and eight years are still very good.

Function of movement

The movement is the mechanical structure that drives the hands, and it is also the most complicated part of the clock. Accuracy and durability are directly affected by the different materials used and the excellent polishing of each part.

Balance in the watch is the name of a mechanical part. It consists of a wheel with an axle arm that can swing back and forth, and there is a spiral hairspring in it. The balance wheel and the hairspring are isomorphic to form the governor of the movement, which has a decisive influence on the time of the watch.

The hairspring connected to the balance wheel drives it to move back and forth, cutting time into exactly the same equal parts.

Domestic fine imitation performance

Although the domestic watch imitation industry has been honed for 20 years so far, there are no fewer than 100 watch factories, and their products only develop output, but do not pay attention to quality. Because most orders in the Pearl River Delta region come from underdeveloped overseas, there is basically no after-sales problem, so many factories produce countless watches.

The famous domestic manufacturers of mechanical watch movements are Beijing Watch Factory, Tianjin Watch Factory and Guangzhou Watch Factory, and the movements made by Guangzhou Watch Factory are called pearl movements. Basically, ordinary imitation watches are all loaded with pearl movements.

In addition to the watch mechanical movements produced by authentic factories in Beijing, Tianjin and Guangzhou, some unknown watch core factories have also been born under the influence of the market, such as Nanning Machine, Dandong Machine and Hangzhou Machine.

The movement of a watch is not as good as that of a pearl. Although the mechanical movement was independently developed and produced in China in the 1960s, and it can meet the international error standard of Class A watches, the movement installed in China's high-end mechanical watches is not independently developed but made in Switzerland due to its simple function.
