A case design reminiscent of the 44GS, which was launched in 1967 and gave birth to the Grand Seiko design philosophy “Grand Seiko Style”. A thick, silver radiant finish to the dial, achieved with techniques unique to Grand Seiko, multi-faceted diamond cut on the hour and minute hands, and multi-faceted cut on the indices.
At first glance, the exquisite form of the watch brings to mind a standard Spring Drive model, but what sets it apart is the blue 24-hour hand contrasting with the white watch face. This watch asserts its GMT capability with a quiet yet unwavering confidence—a powerful partner as you take on the world.
