Second, the watch bumps: Because the watch is exposed most of the time during wearing, it is easy to bump into other hard objects when walking or doing things. If you accidentally bump or fall into the watch in daily use and forcibly hit the watch, it may lead to loose and dislocation of the movement gear and other parts in the watch, and it may also lead to the illegal stop of the mechanical watch.
Third, the hairspring problem: the hairspring fault is also one of the reasons why the mechanical watch stops during normal operation. As we mentioned earlier, some people will stop their watches because of insufficient activity, and if the activity is too large, the winding mechanism will fail because the spring is tightened for a long time. It will also cause insufficient motivation.
