Description

This model is driven by a Grand Seiko’s unique Spring Drive calibre, uniquely pioneered by Seiko Watch Corporation’s watchmakers. Spring Drive generates energy like a conventional mechanical watch with a mainspring but combines this with an electronic regulator to deliver superior precision, never requiring a battery change.

In Spring Drive, the second-hand moves in perfect glide motion, reflecting the natural and continuous flow of time itself. It has a 72-hour power reserve, and a power reserve indicator on the bottom left of the dial.

This model features 44GS Contemporary Design, a contemporary take on the design of the 44GS, which was launched in 1967 and formed the cornerstone of the Grand Seiko design philosophy, Grand Seiko Style.

The combination of a tempered steel hand and a black dial delivers simple and sophisticated quality that wearers can enjoy at any age, coupled with the elegantly radiant case achieved through 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.
