Equipped with a GMT hand, 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.
Housed in a water-resistant stainless steel case with ceramic bezel, a 24-hour GMT hand and Lumibrite indices for exceptional precision and legibility complemented by the smooth motion glide of Spring Drive.
Its bezel is ceramic and therefore resistant to scratches.
The crown is tucked away at the 4 o'clock position and so does not impair the movement of the wrist.
It is water resistant to 20 bar and both the crown and the case back are secured by screw-down mechanisms.
The watch is powered by a Spring Drive movement that is particularly resistant to temperature change and shock.
In every detail, this is the sports watch par excellence.
