Grand Seiko Heritage

Retro-modern mechanical Hi-Beat 36000 GMT

This model incorporates Caliber 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 Caliber 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.
