The short answer

The closest alternative to the Seiko Prospex Marinemaster Marinemaster 1968 Heritage JAMSTEC Limited Edition is the Seiko Prospex Marinemaster Marinemaster 1968 Heritage Diver's Watch ($3,600) — shared caliber (Seiko 8L45) and Same family (Prospex Marinemaster). If price is the constraint, the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition at $1,750 (vs $3,900 for the Prospex Marinemaster Marinemaster 1968 Heritage JAMSTEC Limited Edition) covers most of the same brief. From the independents, the Borealis Watch Co. Jamanta is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Blancpain Bathyscaphe Quantième Complet Phases de Lune ($31,700) is where the same idea goes with a bigger budget.
