The short answer

The closest alternative to the Seiko Prospex Sea 1968 Heritage Diver's GMT is the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch ($1,700) — shared caliber (6R54) and Same family (Prospex Sea). If price is the constraint, the Seiko Prospex Sea covers most of the same brief. From the independents, the Geckota Sea-Hunter Dive Watch is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Norqain Adventure 40mm ($4,283) is where the same idea goes with a bigger budget.
