 * Quartz Oscillator**

A quartz oscillator otherwise known as a crystal oscillator is a mechanism in quartz watches that keeps the time.

The crystal has a property of creating an electric current when deformed, and in turn also starts deforming when a current is passed through.(The piezoelectric effect)The crystals are constructed into the shape of a tuning fork, which have a frequency of 32,768 ± 0.06hz. The watch's battery runs a current through the quartz crystal which makes it resonate at that frequency. This oscillation is then measured and keeps the time constant in the watch.
