The short answer

The closest alternative to the Seiko Prospex Sea Save the Ocean Special Edition is the Seiko Prospex Sea PADI Special Edition ($650) — shared caliber (4R36) and Same family (Prospex Sea). If price is the constraint, the Orient AA02 Diver Watch at $285 (vs $625 for the Prospex Sea Save the Ocean Special Edition) covers most of the same brief. From the independents, the Spinnaker Tesei Titanium is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Seiko Prospex Sea 1970 Heritage Diver's Black Series Limited Edition ($3,300) is where the same idea goes with a bigger budget.
