The short answer

The closest alternative to the Seiko Prospex Marinemaster Marinemaster 1968 Heritage Diver's Watch is the Seiko Prospex Marinemaster Marinemaster 1968 Heritage JAMSTEC Limited Edition ($3,900) — shared caliber (8L45) and Same family (Prospex Marinemaster). If price is the constraint, the Tissot Seastar 1000 at $875 (vs $3,600 for the Prospex Marinemaster Marinemaster 1968 Heritage Diver's Watch) covers most of the same brief. From the independents, the Spinnaker Hull Diver is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Jaeger-LeCoultre Polaris Date Stainless Steel ($11,100) is where the same idea goes with a bigger budget.
