How a battery powers a quartz watch movement

A watch battery sends an electrical current to a small quartz crystal, causing it to electrify the crystal to create vibrations. These vibrations keep the movement oscillating and drive the motor to move the watch hands.

Indication that your watch battery needs to be replaced

When your battery is going bad, often your watch will lose time. Other times your watch will keep perfect time, but the second hand will jump in two to five second intervals indicating that it is time to replace your battery. The last way to know that your battery is dead, is when your watch completely stops.
