Quartz watches are watches powered by a battery or a solar cell. They use an electronic oscillator regulated by a quartz crystal that beats at a specific frequency to keep time. A quartz watch comes with either an analog display or a digital display. Quartz watches are available at almost every price range. They are precise, sturdy, easy to maintain, and more affordable than a mechanical watch. Quartz movements power the majority of watches produced today. Nearly 75% of Swiss watches made are quartz.
