A battery or quartz driven grandfather clock provides the elegance of a traditional grandfather clock without needing to be wound weekly, or reset if you forget to wind your clock. An electronic oscillator and a quartz crystal are used to power the clock keep precise time – often to within 1-2 thousandths of a second per day. Battery powered quartz grandfather clocks use electronic impulses that pass from the battery through a quartz crystal to power the movement of the clock at regular intervals.
