Information

Quartz Watch, also known as quartz vibration electronic watch, is one of the watch types. The main material used in Quartz Watch is quartz crystal. When the quartz crystal is affected by battery power, it will vibrate regularly.

Quartz Watch

Quartz crystal vibrates up to 32768 times per second. People can design a simple circuit to calculate the number of times it vibrates. When it counts to 32768 times, the circuit will send out a message to move the second hand forward for one second. Quartz Watch can also be called a "quartz vibration electronic watch" because it uses the "vibration phenomenon" of quartz plates. When quartz receives an external applied voltage, it has the properties of deformation and expansion. On the contrary, if the quartz is compressed, electricity will be generated at both ends of the quartz. This property is also seen in many crystals, which is called "piezoelectricity". effect". Quartz Watch is the use of crystals that periodically and continuously "vibrate" to bring us accurate time.

How Quartz Watch works

First, power on the quartz chip in the Quartz Watch, and the quartz will vibrate correctly at a frequency of 32768 Hz; then this frequency must be converted to 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 the vibration), follow some signal currents to start the rotor gear, and the second hand on the watch will start.
After that, the beating 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 contain 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 allows Quartz Watch to be mass-produced, 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.
