Working principle of wristwatch: wristwatch is a precision instrument used to indicate time. The principle of this instrument is to use a vibration system with constant period and continuous vibration as the standard. If the time (vibration period) required by the vibration system to complete a full vibration of a watch is known and the number of vibrations is calculated, then the time elapsed after the vibration is equal to the vibration period times the number of vibrations. I.e. time = vibration period × Vibration times
