A Spring Drive watch that has had a strong following ever since its release. It was the first Grand Seiko watch to be powered by Spring Drive, Grand Seiko’s unique calibre, which combines the motive force of a mainspring with the high precision of a quartz watch. In Spring Drive, the second hand moves in perfect glide motion, reflecting the natural and continuous flow of time itself. It has a 72-hour power reserve, and a power reserve indicator on the bottom left of the dial.  The watch face and multi-faceted hands and hour markers seem to change depending on the angle and amount of light, giving this watch its eternal appeal.  Wearers of this watch can enjoy a clear view of the movement through the see-through case back. The watch features a sweeping hand movement, a unique mechanism that differs from mechanical and quartz movement.
