FEATURES
A Spring Drive GMT for the next generation
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.
