If the mechanical watch doesn't work, first check whether the watch has been at rest for a long time. An automatic watch winds automatically according to the swing generated by the opponent's movement. If the watch is in a relatively static state for a long time, it will lose its walking ability and stop walking. Users only need to shake the watch dozens of times or wind it up several times (if there is a function of manual upward adjustment) to restore the stopwatch time. In order to make the automatic watch walk correctly, it should be worn normally for more than 8 hours every day.
But why doesn't the watch suddenly go when it is fully charged? In addition to power problems, mechanical watches are also related to non-running, collision, separation of movement gears, surface magnetism, and drying of oil stains left for a long time. In order to prevent this from happening, the daily wearing care of mechanical watches must be done well.
