Where can I repair my watch in Miyun District?

Objectively speaking, in order to know the accuracy of watches, there are some errors in mechanical watches compared with quartz watches. The coordination and stability of the swing system (including the escapement system and the hairspring system) are the main factors that determine whether it can walk accurately. These are the hardware problems of the movement itself, which we can't avoid, and minor errors are also reasonable. At the same time, the error value provided by the brand is the daily error calculation, not the monthly error! If you say "my watch loses two minutes a month", then there is nothing wrong with your watch. After sale, it is located at Building D 1 1 Floor 2 of World Trade Center in the southwest corner of Guo Mao Bridge.
