In 1988 Seiko introduced their first kinetic watch under the name A.G.S. Kinetic energy is power generated by motion. Seiko's aim was to limit the use of batteries to a minimum in developing this unique feature where the motion of the wearer loads the watch battery. Kinetic energy is an efficient system, environmentally friendly and because the watch battery does not need to be replaced, the water resistance of the watch is guaranteed for a longer period of time.
