Grand Seiko Mechanical Hi-Beat GMT

The hi-beat GMT movement 9S86 is designed, made, assembled, adjusted and tested at the Shizuku-Ishi Watch Studio in where all Grand Seiko mechanical watches are manufactured and assembled, by hand, by the studio’s craftsmen and women. In both performance and appearance, it expresses the very best of Seiko’s mechanical watchmaking. The caliber has a high accuracy of +5 to -3 seconds a day and a power reserve of 55 hours. The GMT hand can be used as a dual time indicator with the hour hand being adjustable independently as the time of day hands continue to mark time. It is the perfect watch for the international traveler.
