How Does a Quartz Watch Work?

A quartz watch is a type of electronic watch that uses a small battery-powered quartz crystal to keep time. Unlike a mechanical watch, which uses a complex system of gears and springs to regulate the movement of its hands, a quartz watch relies on the vibrations of a tiny piece of quartz crystal.

Inside a quartz watch, there is a small battery that provides power to a small electronic circuit board. This circuit board includes a quartz crystal, which is a thin piece of quartz that is cut into a precise shape and size. When an electric current is applied to the quartz crystal, it begins to vibrate at a very high frequency, usually 32,768 times per second.

These vibrations are incredibly regular and predictable, which makes them ideal for keeping time. The electronic circuit board measures the vibrations of the quartz crystal and uses them to regulate the movement of the watch’s hands.

The quartz crystal is also used to power a small motor that moves the hands of the watch. This motor is controlled by a tiny integrated circuit, which receives signals from the quartz crystal and uses them to adjust the movement of the motor.

Overall, a quartz watch works by using the vibrations of a small quartz crystal to keep time and regulate the movement of its hands. The battery-powered electronic circuit board inside the watch measures the frequency of these vibrations and uses them to control the movement of the watch’s motor.
