Seiko Kinetic is the first quartz watch powered by human movement a development so significant it led to the application for more than 50 patents. The process uses an oscillating weight that is rotated by the movement of your wrist: this movement is transformed into a magnetic charge then into electricity which is stored in a tiny capacitor or a rechargeable battery. A Power Reserve Indicator shows exactly how much energy you’ve created.
