The short answer

The closest alternative to the Seiko Prospex Sea Save the Ocean Special Edition is the Seiko Monster ($550) — shared caliber (Seiko 4R36) and Same family (Prospex Sea). If price is the constraint, the Orient FAA02008D9 at $265 (vs $550 for the Prospex Sea Save the Ocean Special Edition) covers most of the same brief. From the independents, the Zelos Blacktip 41 is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition ($1,750) is where the same idea goes with a bigger budget.
