This model incorporates Calibre 9S86, the high-specification movement delivers the same accuracy (-5 to +3 seconds a day) and the same power reserve (55 hours) as the core Calibre 9S85, while also offering the GMT function that the international traveler needs to ensure that the accuracy of the time shown is not compromised when the time zone is changed. The GMT hand shows the time in the home time zone.
The case and bracelet are made with high-intensity titanium, providing a scratch and corrosion resistant finish, making it 30% lighter than stainless steel and a pleasure to wear.
Compared with standard titanium, the case bears a white sheen akin to stainless steel, which can be maintained throughout the life of the watch.
The stunning aesthetic of the watch—which carries the essence of 'Grand Seiko Style', the embodiment of the Grand Seiko design philosophy which started with the 44GS—consists of a distortion-free, wide mirror surface, and an intricate, multifaceted shape, providing a beautiful luster.
A visibly lightweight appearance is created with a steady stripe design that links well with the unique lightweight high-intensity titanium materials that are used in this watch.
