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, which combines the motive force of a mainspring with the high precision of a quartz watch.

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.

The essential characteristics of Grand Seiko; precision, legibility, comfort and durability are nowhere more prominently expressed than in this new creation. The Spring Drive Chronograph may well be the most accurate luxury chronograph in the world, offering a precision of ten seconds a month. The dial is supremely easy to read, thanks to the diamond-cut hands and markers, extended GMT and minute hands and the Lumibrite inserts on the hands as well as the markers.

The watch is also a delight to wear, primarily because of the light-weight hybrid titanium-ceramic case and bracelet. As the zirconia ceramic parts are raised slightly above the level of the titanium, the bracelet is virtually impervious to scratches and will retain its pristine appearance just as long as the watch case itself. Remarkably, given the technical difficulty of polishing ceramics, the ceramic parts in the centre of the bracelet are polished to a mirror finish and the signature Grand Seiko sharpness of the angles on each component has been achieved.

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.
