First of all, make sure what's wrong with the watch. The common problem with quartz watches is that they are not allowed to go. You can try degaussing. If you don't leave, it should be that the battery is dead and you can change it. There are many reasons for the problems of mechanical watches, such as time adjustment, insufficient winding, inaccurate or secretly stopping, slow walking and so on. The internal problems of the movement need to be detected on the watch calibrator, and the problems can be solved if they are found out. If it is an appearance problem, it is relatively simple, such as replacing a broken watch mirror, polishing and renovating the shell or repairing the buckle of the strap.
If there is anything wrong with your watch, you can take it to Guangcheng Watch Line, Room 2 1 Floor 2 109, North Tower of Suning Plaza, Renmin Middle Road, Wuxi City. Please ask the master to help you look at the specific situation.
