The short answer

The closest alternative to the Seiko Prospex Sea Save the Ocean Special Edition is the Seiko Prospex Sea PADI Special Edition ($625) — shared caliber (4R35) and Same family (Prospex Sea). If price is the constraint, the Orient Kanno at $320 (vs $650 for the Prospex Sea Save the Ocean Special Edition) covers most of the same brief. From the independents, the Phoibos Leviathan is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Seiko Prospex Sea ($1,500) is where the same idea goes with a bigger budget.
