Seiko Prospex 1968 Heritage Diver’s GMT 60th Anniversary Stainless Steel Watch

The Seiko Prospex 1968 Heritage Diver’s GMT 60th Anniversary pays tribute to a landmark in the brand’s diving legacy—its first hi-beat Diver’s watch with a one-piece case from 1968. This 2025 reinterpretation is crafted in stainless steel with a super-hard coating, and features a ceramic bezel with a diving scale, as well as a GMT function capable of tracking three time zones. Powered by the in-house 6R54 automatic GMT calibre with a 72-hour power reserve, it offers 300m water resistance and introduces a micro-adjustable clasp on a short-pitch bracelet for the first time in a Prospex model.
