Quartz watches are stabilized by a chronotropic crystal with a resonant frequency of 32,768 Hz. The oscillator circuit generates a pulse signal of 32768Hz, which is divided by 15 times to get a second signal, which drives the single-phase stepping motor, and drives the hour hand, minute hand and second hand through the gear transmission system to display the time.

The winding spring produces elastic deformation, and then the mechanical setting controls the recovery of elastic deformation, that is, the walking of the second hand. The mutual meshing of gears constitutes the relative position of hour hand, minute hand and second hand, so that the time can be displayed.

Electronic watches, like all other clocks and watches, use repeated and continuous vibrations. The difference is that the mechanical watch is driven by the elastic deformation of the spring, which drives the timer in the watch to vibrate and time; An electronic watch is powered by a battery, and then converts electric energy into magnetic energy. A sensitive device (such as a timing transistor) is selected as a switch to drive the timer to keep vibrating. At the same time, the magnetic energy is converted into mechanical energy, which drives the pointer to rotate (or change the number) and displays the time.
