A **quartz watch** is a type of timepiece that uses a quartz crystal to keep time. The crystal oscillates at a precise frequency when subjected to an electric charge, which is typically supplied by a small battery. This oscillation helps regulate the movement of the watch, making it incredibly accurate, usually losing or gaining only a few seconds per month. Key features of quartz watches include: - **Accuracy**: More precise than mechanical watches due to the consistent vibrations of the quartz crystal. - **Low Maintenance**: Powered by a battery, so there is no need for winding. - **Affordability**: Typically less expensive to produce and purchase than mechanical watches. - **Durability**: Generally more resistant to shocks and vibrations compared to mechanical counterparts. Quartz watches can come in both **analog** (with hands) and **digital** (displaying numbers) formats.
