Grand Seiko
Hi Beat 36000 SBGH257 Limited Edition

This professional diver's model features the Caliber 9S85 high-precision 10-beat mechanical movement in a case that can withstand pressures encountered in saturation diving, down to a depth of 600 meters.
The rotating bezel has a knurled, non-slip finish so that the bezel can be properly gripped and turned by a thick diving glove. The indicators use a design that makes their scale easier to read accurately.
To achieve an operating feel that will not change, even if the watch is well-used, the main components (display plate, watch glass locking ring, bezel locking ring, and bezel) are designed so that they can be disassembled for maintenance.
Using a pure iron dial guarantees the watch's magnetic resistance, for peace of mind when diving and in day-to-day use.
The case is finished with Seiko's unique Zaratsu technique. The sharp edge-lines and undistorted mirror surfaces of the case overlap to create a multi-faceted effect, giving the watch an impressive shine.
The dial design features a pattern of dots that symbolize a cloud of sparkling, rising bubbles. Only this model has the Grand Seiko Blue dial color and toughened silicone band of the same color.
The dial and strap of the limited edition are made in the exclusive color that signifies craftsmanship and tradition in Japan and is the signature color of Grand Seiko. It comes with an extra-strength silicone strap, in the deep Grand Seiko blue to match the dial so that you can change the appearance of the watch at will.
