Autoquarz

In Autoquartz watches the modern technology of quartz watch connects with the classical technique of the automatic mechanical drive. The precision advantages of the former complement each other with the environmentally friendly battery freedom of the latter. So one could speak of a hybrid technique.

Towards the end of the 1980s, the Japanese company Seiko brought the system AGS (Automatic Generating System) on the market. The movements of the weight segment (rotor) is transferred with the help of a high-ratio gearbox to a tiny electrical generator. This charges, depending on the version, either a capacitor or a rechargeable lithium-ion battery. A protection unit prevents the energy storage from being overloaded. Autoquartz watches by Seiko are marketed under the name "Kinetic".

Since 1996 there existes a comparable system by the Swiss ebauche movement manufacturer ETA.

In the field of high-end luxury watches the Autoquartz technology could not yet assert itself.
