This Grand Seiko diver’s watch is powered by the brand’s iconic Spring Drive movement, one of the most significant developments in recent watchmaking which took 28 years to develop.

With a superior level of precision, Spring Drive generates energy with a mainspring combined with an electronic regulator, never requiring a battery change. Seiko Watch Corporation pioneered Spring Drive which is only available in their timepieces.

The high specifications of this diver’s watch are in accordance with the latest strict international ISO 6425 diver’s watch requirements for quality and clear visibility.

Water resistant to a depth of 200 metres, this watch features LumiBrite for high visibility underwater and in less well-lit situations. Designed for use in some of the most unforgiving environments, the rotating bezel is removable for simple maintenance, while the area around the crown has been crafted to ensure that residue can be easily washed off.

With a mirror-finished case achieved through Zaratsu polishing, a lustrous rotating bezel, and multi-faceted cut indices, this watch is unmistakably Grand Seiko in its appearance, high specifications and durability.

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