Grand Seiko 60th Anniversary Limited Edition Professional Diver's 600M

Grand Seiko introduces a new generation Spring Drive calibre that is slimmer, even more precise and has a greater power reserve. Calibre 9RA5 takes Spring Drive technology to a new level of excellence and opens a new era in the history of Grand Seiko.
Calibre 9RA5's thin profile is made possible by the re-design and re-positioning of the Magic Lever. In the new calibre, the new Offset Magic Lever is positioned away from the centre of the movement to reduce its thickness. Remarkably, this is achieved with no loss of winding efficiency.
Calibre 9RA5 may be slim but it has enhanced rigidity and shock resistance thanks to the new layout of the gear train towards the centre of the movement and a central bridge that holds them together. This One-piece Centre Bridge achieves a shock resistance that meets the ISO standard for diver's watches.
The movement incorporates two barrels which deliver a power reserve of up to 120 hours. They are different sizes so as to deliver the torque required for the five day power reserve while optimising the use of the limited space within the movement.
Calibre 9RA5 has an accuracy rate of ±10 seconds per month thanks to a new IC package and to the selection of highly stable quartz oscillators that have gone through a three-month ageing process.
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 calibre that powers it.
The dial colour is Grand Seiko blue, a special colour that symbolises 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 will be available worldwide in August as a limited edition of 700.
