The 1968 Heritage Diver’s GMT is Seiko’s modern reissue of the 1968 62MAS, and the 6R54 is the movement that makes it a traveler: a true GMT with an independently adjustable local hour hand and 72 hours of power reserve. The blue dial and case shape nod hard to the original. Sapphire crystal with AR coating. It is the heritage diver that doubles as a GMT. 42 mm, 13.3 mm thick, 48.6 mm lug-to-lug. Acquired 2026-02-07.
