Description
A professional diver watch, made the Grand Seiko way.
This professional diver’s model features Caliber 9S85 which has a precision of +5 to -3 a day. It is 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 and even the bezel has a four-part design that makes for easy disassembly and re-assembly.
The dial is made of pure iron in order to protect the movement from the harmful effects of magnetism. It delivers safe and secure use during diving and, thanks to the lightness of the titanium, every-day usability is also assured.
It has the distinctive clean edges and distortion-free mirror surfaces that only Zaratsu polishing can deliver.
