The short answer
The closest alternative to the Seiko Prospex Sea Save the Ocean Special Edition is the Seiko Prospex Sea JAWS 50th Anniversary Limited Edition ($795) — shared caliber (Seiko 4R36) and Same family (Prospex Sea). If price is the constraint, the Orient Sport Watch at $245 (vs $625 for the Prospex Sea Save the Ocean Special Edition) covers most of the same brief. From the independents, the Spinnaker Wreck Automatic 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.
