DelRay Auto-Quartz Movement

The Seiko YT57 Auto-Quartz (Kinetic) movement provides the benefits of both automatic and quartz watches.  The automatic movement is the typical rotating counter weight, and is visible via a glass case back.  Instead of the rotating mechanism winding a spring, the YT57 stores energy in a small capacitor.  This electrical energy is then used to power the quartz operation of the watch; which provides extremely reliable time keeping.  This combination of rotation mass converting to electrical energy is a true hybrid approach.
