Grand Seiko Heritage 'Mount Iwate Pattern Dial'
This model incorporates a beautifully delicate and polished finish 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 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.
