How does a quartz watch works?

Answer 1

It works by using the piezoelectric effect: if a small voltage is applied to a specially prepared crystal of quartz it vibrates at a definite and almost constant frequency which can be used to power a tiny motor to turn the hands of the watch.

Answer 2

Quartz has the property of being piezo electric. It can bend with electricity or produce electricity by bending. Cutting a quartz crytal to precise dimensions will allow it it resonate when stimulated.

Electronics in the watch use the crystal in an oscillator circuit to produce a frequency, typically 32,768Hz. This can be divided down using electronic counters, to give one pulse every second.

In an analogue watch, this one pulse is applied to a stepper motor which moves the second hand, one second.

Gears from the second hand drive the minute and hour hands like a conventional watch. Digital watches use an LED or LCD display, driven by counter circuits that advance one second at a time.

Answer 3

A quartz watch works by using a small piece of quartz crystal to regulate the timekeeping. When an electric current is applied to the crystal, it vibrates at a precise frequency, which is then converted into regular electronic pulses to drive the watch hands. This allows for accurate timekeeping without the need for mechanical parts.
