This diver’s watch is powered by Grand Seiko’s unique Spring Drive calibre, which combines the motive force of a mainspring with the high precision of a quartz watch.
The watch is water resistant to a depth of 200 meters and utilises LumiBrite for increased visibility of the hands and index. Designed for use in some of the most unforgiving environments, the rotating bezel is removable for simple maintenance while the area around the crown has been crafted to ensure that residue from dirt, sand, or seawater can be easily washed off.
With a mirror-finished case achieved through Zaratsu polishing, a lustrous rotating bezel, and multi-faceted cut indices, this watch is unmistakably Grand Seiko in its appearance, high specifications and durability.
