The short answer

The closest alternative to the Seiko Prospex Sea 1965 Heritage Diver's Save the Ocean Special Edition is the Seiko 62MAS ($1,200) — shared caliber (Seiko 6R35) and Same family (Prospex Sea). If price is the constraint, the Seiko Prospex Sea at $595 (vs $1,250 for the Prospex Sea 1965 Heritage Diver's Save the Ocean Special Edition) covers most of the same brief. From the independents, the Geckota Sea-Hunter Dive Watch 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.
