[ 9R Spring Drive ]



A Spring Drive GMT high-intensity titanium model

This model is driven by a Grand Seiko’s unique Spring Drive caliber, which combines the motive force of a mainspring found in mechanical watches with the high precision of a quartz watch.

The watch features a rotating bezel with high-quality sapphire glass on the surface of the ring, providing a sense of transparency, breadth and depth. With a red GMT hand backed by a sharp black dial, the watch inherits the design characteristics of the stainless steel model, combined with superior lightness and strength of a high-intensity titanium case and band, and gold hour markers, hands and inscription.
The large case combined with lightweight high-intensity titanium makes for a highly comfortable fit.
