A Spring Drive model with a sharp, crisp impression combining ceramic and high-intensity titanium
This watch features a luxury sports design and a remarkable new hybrid titanium-ceramic bracelet construction.
The flat shape of the case was developed with the aim of making the most of the unique characteristics of zirconia ceramic.
Despite the difficulties of polishing ceramics, the beautifully crafted ceramic edges on the polyhedral shape are polished to a mirror finish and produce the intricate overlapping reflections that are the characteristics of the Grand Seiko design.
The band's combination of these two different materials serves a practical purpose while also accentuating the design. 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.
The second hand, minute hand, GMT hand and markers on the black dial are all finished with LumiBrite inserts to ensure high legibility.
