The working principle of quartz meter is that the integrated circuit and a quartz resonator provide energy and control the time display.
Quartz will vibrate when placed in a vibrating circuit. Under certain conditions, it will transmit its own frequency to the circuit. If this characteristic is applied to the quartz movement, the electric energy can be transformed into power through the quartz oscillator. The movement can be completed by mass production of circuit boards with mechanized equipment, and then equipped with resistors and capacitors. Then the watch case, glass and strap can be installed, and a quartz watch can be roughly assembled.
All quartz watches are equipped with a battery. It provides energy for an integrated circuit and a quartz resonator, vibrating 32768 times per second. There's something faster than this. Integrated circuit is the "brain" of watch. It controls the vibration of quartz resonator and acts as a frequency divider. 32768 vibrations were split in half 15 times to produce one pulse per second. With the "raw material" of one second, the clock can be driven. The application of quartz crystal enables the mass production of watches. Not only the production speed is much faster than before, but also the price decreases. About 500 million watches can be manufactured every year for global use. （DanYingBiaoYuanLi）
