Description
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.
Designed in harmony with the classic case, the retro-modern dial is inscribed with a 1/5 second scale that is unique to a 10 beat model. The result is a design finish that is both fine and elegant.
The long and slim markers provide a clean and refined expression.
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.
