Why Quartz in Watches?
Quartz was first introduced to the watchmaking scene in 1927, when a quartz clock was invented before the wristwatch was even thought of. When quartz crystals are under mechanical stress, they generate an electric charge, an effect known as piezoelectricity. Quartz is able to bend or even change its shape once piezoelectricity occurs. It can convert electrical voltage back and forth in order to maintain a watch’s frequency. Quartz crystals, when cut to a consistent size and shape, have the ability to vibrate at thousands of times per second. This makes them very stable resonators, commonly used today for keeping accurate time. The precise standard of frequency, the stability of an oscillator used for frequency calibration, allows quartz to maintain and regulate the movement of a watch, so that it is extremely accurate. Even digital watches are controlled by quartz’s ability to slow time. Most quartz used in watches and other electronic devices is a synthetic, made specially for the pur
