The short answer
The closest alternative to the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition is the Seiko Prospex Sea 1965 Heritage Diver's Save the Ocean Special Edition ($1,250) — shared caliber (Seiko 6R35) and Same family (Prospex Sea). If price is the constraint, the Orient 75th Anniversary RA-TX0210L10B at $375 (vs $1,350 for the Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition) covers most of the same brief. From the independents, the Borealis Watch Co. Jamanta 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.
