Working principle of watch: watch is a kind of precision instrument used to indicate time. The principle of this instrument is to use a vibration system with constant cycle and continuous vibration as the standard. If we know the time (vibration period) that the vibration system needs to complete a full vibration of the watch and calculate the number of vibrations, then the time after so many vibrations is equal to the vibration period multiplied by the number of vibrations. I.e. time = vibration period × Number of vibrations
