The short answer

The closest alternative to the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition 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 CWC 1980 RN Divers Automatic Re-Issue Watch is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Seiko Prospex Marinemaster Marinemaster 1968 Heritage Diver's Watch ($3,600) is where the same idea goes with a bigger budget.
