A Spring Drive GMT for Smart Men of the World
At first glance, this watch looks like a standard Spring Drive model. With a case design reminiscent of the 44GS, which launched in 1967 and gave birth to the Grand Seiko design philosophy “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.
But the beautiful blue steel of the 24-hour hand on the handsome clock face sets this watch apart. It asserts its GMT capability with a quiet yet unwavering confidence—a powerful partner as you take on the world.
