What is autoquartz?

Autoquartz is a type of watch movement that was developed by Seiko in the late 1990s. It combines the accuracy of quartz movements with the convenience of automatic movements.

Autoquartz movements have a quartz oscillator that is powered by a rechargeable battery that is charged by the motion of the wearer's wrist. The battery is estimated to last between 2 and 5 years, depending on usage.

Autoquartz movements also have a mechanical rotor that winds the watch's mainspring. This means that the watch does not require manual winding or a battery replacement like traditional quartz or mechanical watches.

Autoquartz movements are known for their accuracy, with some models able to keep time within a few seconds per year. They are also popular for their convenience and low maintenance requirements.

Some notable watches that use autoquartz movements include the Seiko Kinetic and the Tissot T-Touch.
