Quartz watches owe their accuracy and reliability to a small battery that generates an electrical current.

This current vibrates a piece of quartz at a precise frequency, sending a signal to the watch that translates to a movement of the watch's hands.

In the late 1960s, Seiko introduced a new form of watch power that changed timekeeping forever.

Quartz watches quickly became popular thanks to their accuracy and the elimination of the need for manual winding.

They require minimal maintenance or upkeep, making them a convenient choice for everyday use.
