What is the working principle of a quartz watch?
First, power on the quartz plate in the quartz watch, and the quartz will vibrate correctly at a frequency of 32768 Hz; then this frequency must be converted into a signal current cycle of 1 Hz (a current change in one second). Increase the amplitude of some signals (due to the weak current generated by vibration), follow some signal currents to start the rotor gear, and the second hand on the watch will start.
After that, the movement of the minute hand and hour hand is related to the principle of the mechanical structure. For example, if the second hand jumps 60 times, the minute hand will jump once.
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 is something faster than this. The integrated circuit is the “brain” of the watch. It controls the vibration of the quartz resonator and acts as a frequency divider. The 32768 vibrations are divided in half 15 times to achieve one pulse per second. With the “raw material” of one second, it can drive the clock.
The application of quartz crystals enables the mass production of watches, not only the production speed is much faster than before, but the price also drops. Approximately 500 million watches can be manufactured every year for global use.
The time and second hand of a quartz watch is one frame and one jump, and the time is very accurate. Generally, the error is required to be within 15 seconds, and there are two kinds of three hands and two hands.
