The Hi-Beat 36000 Professional 600m Diver’s

The first ever mechanical diver’s watch from Grand Seiko

For many years, Grand Seiko’s Spring Drive diver’s watch has been in great demand from recreational divers, but, perhaps surprisingly, there has never been a Grand Seiko mechanical diver’s watch. Until now. For 2017, Grand Seiko’s high standards are expressed in a professional diver’s watch for the first time. With a titanium case, a 9S hi-beat caliber and remarkable anti-magnetism, this new creation, with the Grand Seiko logo at the twelve o’clock position, pushes back the boundaries and takes Grand Seiko into an entirely new realm.

All the characteristics of Grand Seiko are here. Precision of -3 to +5 seconds a day, superb legibility, high durability, thanks to the high-intensity titanium case and bracelet and the distinctive clean edges that only Zaratsu polishing can achieve. The case is designed for saturation diving, with the valve-free helium resistance that results from Seiko’s innovative technologies, including the heavy duty construction and the L-shaped gasket. The grooves on the rotating bezel are extended for secure use, even with thick gloves. The bracelet has a sliding extension setting to accommodate pressure changes.

The dial is also purpose built for this specialist use. It is made of iron to protect the movement from the harmful effects of magnetism and delivers magnetic resistance of 16,000 A/m. The whole watch and all its components are built for long-term use; 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.
