Grand Seiko Heritage 'Mt. Iwate' Mechanical Hi-Beat 36000 GMT SBGJ203
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'Ñthe embodiment of the Grand Seiko design philosophy which was first established for the 44GS in 1967Ñand 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 9S86:
This 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.
Pulling the crown out by one notch enables the hour hand to be adjusted without stopping the second hand so that the highly accurate timekeeping delivered by the Hi-Beat 36000 is not lost. Calibre 9S86 is the embodiment of the Grand Seiko ideal of high accuracy, maintaining exceptional precision in both the essential time display and the GMT function.
