Quartz is an oxide with a composition of silicon dioxide (SiO2). Quartz is placed in an oscillating circuit, it will vibrate. Under certain conditions, it transmits its own frequency to the circuit. If this characteristic is applied to the quartz movement, the electric energy can be converted into kinetic energy through the quartz oscillator, and the circuit board can be mass-produced by mechanized equipment, and then the resistor and capacitor can be used to complete the movement. Then the case,lass and strap can
