This model is powered by the 9S86 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 black dial features a ‘Mount Iwate pattern’ showing the ridgelines of the magnificent mountain visible from the Shizukuishi Watch Studio where all Grand Seiko mechanical timepieces are made. It expresses the beauty of winter mountain scenery.

The exterior design is a modern take on the stunning ‘Grand Seiko Style’ the embodiment of the Grand Seiko design philosophy which was first established for the 44GS in 1967. It features a distortion-free, wide mirror surface achieved by our signature Zaratsu polishing.

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.
