Classical styled Spring Drive watch
This simply finished model with no crown guard is driven by a Grand Seiko’s unique Spring Drive caliber, 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.
Its classic style consists of box-shaped sapphire glass, off-while color of the dial, power reserve indicator, crocodile strap and so on.
