A quartz watch is a device that uses an electronic oscillator that is regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, making quartz watches significantly accurate than mechanical watches. A digital logic counts the cycles produced by the oscillator and displays time in units of hours, minutes, and seconds. A typical quartz watch have an accuracy of ±15 seconds per 30 days (within a normal temperature range) when worn near the body. In modern quartz watches, the quartz crystal oscillator is in the shape of a small tuning fork.
In 1980, quartz timekeepers have become the world's most widely used timekeeping technology, initiating the boom of less expensive quartz watches. Since then, most watch manufacturers have utilized and developed quartz technology to provide better timekeeping devices uniquely their own.
