quartz clock

A quartz clock uses a tiny piece of quartz crystal that vibrates at a precise frequency when an electric current passes through it. This consistent vibration acts as a highly accurate timekeeping reference. The clock’s electronics count these vibrations and convert them into a regular electrical pulse, which drives the clock’s hands or digital display. Because quartz crystals vibrate with remarkable stability, quartz clocks are very accurate and reliable, making them a common choice for everyday timekeeping devices.
