The short answer

The closest alternative to the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch is the Seiko Prospex Sea 1968 Heritage Diver's GMT ($1,500) — 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 Henry Archer Nordsø is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Yema Superman Tourbillon CMM.31 Limited Edition ($13,000) is where the same idea goes with a bigger budget.
