Watch is a precision instrument used to indicate time. The basic part of the electronic meter is composed of electronic elements. The working principle is designed according to the physical phenomenon of electromagnetism and magneto-electroelectricity, that is, from electric energy to magnetic energy, and then from magnetic energy to mechanical energy to drive the operation of time division needle to achieve the purpose of timing.
