Seiko Grand Seiko GMT Spring Drive SBGE001

Seiko Grand Seiko GMT Spring Drive SBGE001 dating to 2007 with complete box and papers along with Grand Seiko pen and refill. The later model is the SBGE201 which now retails fo £5650. This SBGE001 howwerver is built to the same specifications and standards as the latest model. Equipped with a GMT hand and a rotating bezel, this watch features Grand Seiko’s 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.

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.
