V. Impact and fall

1.    A mechanical watch is a very sophisticated instrument that collects energy through a spring winding and then delivers energy to the balance spring system through the transmission system for timing, and then displays the time through the drive train and hands. Therefore, in a small space of no more than a few centimeters per piece, there may be hundreds of parts, and the damage, looseness or displacement of one of the parts may cause the mechanical watch to be inaccurate or even stopped.

2.    The external impact will also cause the quartz watch battery to be disconnected from the positive and negative poles. Therefore, after the watch is hit and dropped, it is recommended that the watch be sent to the designated service center for inspection.
