A professional dive watch with a next-generation Spring Drive movement

Housed in a masterfully crafted high-intensity titanium case, Grand Seiko introduces a new generation Spring Drive caliber that is slimmer, more precise and has a greater power reserve and resistance to shock. Caliber 9RA5 takes Spring Drive technology to a new level of excellence and opens a new era in the history of Grand Seiko.

The finishing of 9RA5, also, the movement has a beauty that is uniquely Japanese and is inspired by the natural environment of the studio where it is made. The jewels echo the glittering stars that sparkle especially brightly during the early days of winter in the surrounding mountains and the delicate texture of the movement's surfaces reflect the frost that winter brings to the trees.

The case is in high-intensity titanium, which is 40% lighter than steel and more impervious to scratches. The power reserve is at the 10 o'clock position and the indicator is divided into five parts to show exactly and clearly how many days of power are left. The case, crystal and bezel are all designed for easy and safe disassembly for the maintenance that a professional diver demands. It is a watch entirely worthy of the high performance of the new caliber that powers it.
The dial color is Grand Seiko blue, a special color that symbolizes the brand. It is a special specification unique to limited edition.

The watch is presented in a special Grand Seiko 60th anniversary box with an interchangeable blue silicone strap. It is limited to 700 pieces.
