Equipped with a GMT hand, this watch features Grand Seiko’s unique Spring Drive calibre, which combines the motive force of a mainspring with the high precision of a quartz watch. The second hand movement over the black dial, further highlights a glide motion that reflects the natural and continuous flow of time itself.
The high-quality sapphire glass on the surface of the ring provides a strong sense of transparency, breadth and depth.
Always ready for action, the Grand Seiko Sport collection blurs the lines between function and form, allowing you to keep track of time, no matter where your next adventure takes you.

Protected by sapphire crystal glass, this high precision timepiece is driven by a powerful Spring Drive movement, is water resistant to 200 meters and offers a 72-hour power reserve.
Secured with a stainless steel bracelet with a three-fold clasp.
