[ 9R Spring Drive ]



A Spring Drive GMT for the next generation

Equipped with a Aguja de GMT, this watch features Grand Seiko’s unique Spring Drive caliber, 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.
