quartz movement

A quartz movement in a watch uses a tiny piece of quartz crystal to keep time accurately. When you wind or replace the battery, electricity flows through the crystal, causing it to vibrate at a precise frequency (usually 32,768 times per second). These vibrations are converted into regular electrical pulses, which drive the watch's motor to move the hands at a consistent rate. Quartz movements are known for their accuracy, low maintenance, and affordability compared to mechanical watches, making them popular for everyday timepieces.
