Today, the meticulous standards of Grand Seiko are expressed in a professional diver's watch for the first time. With a titanium case, an exclusive 9S hi-beat calibre and exceptional anti-magnetism, this new creation, with the Grand Seiko logo at the noon position, pushes back the boundaries and takes Grand Seiko into an entirely new realm.

A professional diver's watch made the Grand Seiko way

All the characteristics of Grand Seiko are here. The outstanding precision of -3 to +5 seconds a day, superb legibility, and high durability, thanks to the high-intensity titanium case and bracelet and the distinctive clean edges that only Zaratsu polishing can achieve. This is unmistakably a Grand Seiko and yet no compromise is made in satisfying the needs of the professional diver. 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. Even the dial is purpose-built for this specialist's use. It is made of iron to protect the movement from the harmful effects of magnetism and delivers a 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.

A limited edition leads the way forward.

The Grand Seiko Hi-Beat 36000 Professional 600m Diver is offered in two variations. The first is a limited edition that is offered with an extra-strength silicone strap alongside the high-intensity titanium bracelet. The strap is in the deep Grand Seiko blue to match the dial. Just five hundred of this limited edition will be made. The second version has a black dial and will be a permanent part of the Grand Seiko collection. Both versions will be available from August 2017. For the full line-up, please visit https://bezelcasedial.com/
