Movement
| Movement type |
Autoquartz / Kinetic
Hybrid technology combining a quartz movement with mechanical self-winding: a rotor drives a miniature generator that charges a capacitor, which then powers the quartz oscillator. Marketed by Seiko as 'Kinetic' (1988) and by ETA as 'Autoquartz', it merges automatic convenience with quartz precision and no battery changes.

Automatic (Rotor-Driven)
Self-winding via a rotor whose motion winds the mainspring through a transmission gear train. The specific rotor configuration (central, micro, peripheral, bumper) is catalogued separately under Rotor Type. Standard on the vast majority of mechanical wristwatches since the mid-20th century.
