The short answer
The closest alternative to the Seiko Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition is the Seiko Prospex Sea 1965 Heritage Diver's Watch PADI Special Edition ($1,550) — shared caliber (6R55) and Same family (Prospex Sea). If price is the constraint, the Seiko Prospex Sea covers most of the same brief. From the independents, the Zelos Swordfish 3 is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the DOXA SUB 300 ($2,890) is where the same idea goes with a bigger budget.
