Background

The watch movement is a clockwork which utilizes the power generated by the left-right swing of an automatic disc at the bottom of the movement to drive the clockwork to generate energy, but the thickness of the relative watch is thicker than that of a common watch with a hand clockwork. A wristwatch, also known as a wristwatch, is an instrument worn on the wrist for timing or displaying time. The watch is a precision instrument for indicating time, and the principle of the instrument is that a vibration system with constant period and continuous vibration is used as a standard. If the time required for the vibration system to complete a single full vibration (vibration cycle) is known and the number of vibrations is calculated, the elapsed time after such a number of vibrations is equal to the vibration cycle times the number of vibrations.

Mechanical watches are precision instruments, most of mechanical watches are very careful in the use process, but when the watches are accidentally dropped, the internal movement of the mechanical watch is damaged due to the vibration generated by falling to the ground, and the normal use of the mechanical watch is affected.
