Description

This model is powered by the 9S85 Mechanical movement; sophisticated watchmaking innovation through its precision controlling mainspring, the hairspring, and the escapement. Together the movement showcases the power and dynamism of the Mechanical Hi-Beat 36,000.

The watch was built to withstand pressures encountered in saturation diving, down to a depth of 600 meters. The grooves on the rotating bezel ensure a firm grip even with thick diving gloves. Luminous markers at every ten second point on the dial ensure the legibility on which the safety of the deep sea diver depends.

Every component is built to last, but all divers know that their watch needs regular maintenance, just like every other device on which his or her life may depend. This is why the case, stem and crown are designed for secure servicing including the bezel with a four-part design ensuring easy disassembly and re-assembly.

The dial is made of pure iron in order to protect the movement from harmful effects of magnetism. It delivers safe and secure use during diving while the lightness of titanium ensures a comfortable everyday wear. The case features distinctive clean edges and distortion-free mirror surfaces that only Zaratsu polishing can deliver.

Grand Seiko: beautifully, precise Japanese watchmaking, from the pinnacle of Seiko Watch Corporation’s in-house manufacture. Every Grand Seiko features signature high standards of Japanese precision, durability and legibility, handcrafted by Takumi artisans.
