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 one second a day. 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 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 center of the bracelet are polished to a mirror finish and the signature Grand Seiko sharpness of the angles on each component has been achieved.
