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). Quartz movements used by TAG Heuer are some of the most reliable and accurate made in Switzerland.

They are also distinguished by excellent resistance to shocks and magnetic fields. The batteries for TAG Heuer quartz movements have a service life of at least two years. END-OF-LIFE INDICATOR: For increased security, all TAG Heuer quartz watches(except chronographs) with an end of battery life indicator (EOL).

When the battery shows signs of weakening, the seconds hand starts making four-second jumps every four seconds. However, the movement continues to display the exact time until the battery is exhausted.
