‘Deep-Black’ Spring Drive [SBGA467G]

This deep black dial timepiece is powered by the Spring Drive movement, 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. Spring Drive is only available in Seiko Watch corporation timepieces. The second hand moves in perfect glide motion, reflecting the natural and continuous flow of time itself.

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.’
