A quartz movement is powered by a battery. Its regulator (time-measuring device) is a quartz crystal. An electrical current causes the crystal to vibrate very consistently and at a very high frequency (32,768 times per second). This gives the movement almost perfect precision (a variation of only a few seconds per month.)
