This model incorporates Calibre 9S86, the high-specification movement that 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 exterior design is a modern take on the stunning ‘Grand Seiko Style’—the embodiment of the Grand Seiko design philosophy which was first established for the 44GS in 1967—and features a distortion-free, wide mirror surface throughout.
A beautifully delicate and polished finish has been created on the dial, with a ‘Mount Iwate pattern’, inspired by the many-ridged contours of the Mt. Iwate, the mountain that is visible through the windows of the Shizuku-Ishi Watch Studio where Grand Seiko mechanical watches are made.
Calibre 9F82:
Offering the same functionality as the standard Caliber 9F62, Caliber 9F82 is equipped with a slightly larger movement to fit the increased size of its case.
The quartz watch, redefined to the Grand Seiko Standard. To meet the high standards of Grand Seiko, the 9F quartz movement has enhanced precision and durability, made possible by innovations in every aspect of the movement. This might well be the most advanced quartz movement in the world.
