Working principle of the watch. The watch is a precision instrument used to indicate time. The principle of the instrument is to use a vibration system with constant cycle and continuous vibration as the standard. If the time (vibration period) required for the vibration system to complete one full vibration is known and the number of vibrations is calculated, the time after such a number of vibrations is equal to the vibration period multiplied by the number of vibrations. I.e. time = vibration period × Number of vibrations
