Description

This diverÕs watch is powered by Grand SeikoÕs 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 utilizes Lumi Brite 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.

Calibre 9R65:

Grand Seiko unveiled Spring Drive in 1999, but its lack of a sufficiently effective automatic winding mechanism and 72-hour power reserve prevent its adoption in the Grand Seiko line. After a further four years of development, the first Grand Seiko 9R Spring Drive was created.

The winding system and drive time were improved from the existing 48-hour manual winding system to an automatic 72-hour power reserve. The automatic winding mechanism uses Seiko's original Magic Lever mechanism developed in 1959, but with improved productivity, maintainability, and durability to enhance winding efficiency.

Calibre 9R65 is currently the most standard of the 9R Spring Drive movements, and is used in many Grand Seiko models.
