A tribute to driving Japan's high mountain passes

Grand Seiko's signature Mt. Iwate dial comes to life in a lush, effervescent green, which perfectly complements the watch's namesake Tōgè, meaning 'mountain pass,' symbolizes a navigable route through a mountain range, subtly evoking the imagery of a spirited drive over the numerous ridges of Mt. Iwate in Northern Japan.

A gold-tone GMT hand contrasts beautifully against the verdant dial, resulting in a highly legible design that allows for easy tracking of two distinct time zones via a 24-hour ring. The case—with its comfortable curved design, box sapphire crystal, and tapering lugs—calls back to the very first Grand Seiko watch from 1960.

Powering the watch is Caliber 9S66, which features automatic winding, GMT functionality, 72 hours of power reserve, and accuracy of +5/-3 seconds a day.
