The short answer
The closest alternative to the Seiko Monster is the Seiko Prospex Sea Save the Ocean Special Edition ($550) — shared caliber (Seiko 4R36) and Same family (Prospex Sea). If price is the constraint, the Orient FAA02007B9 at $265 (vs $550 for the Monster) covers most of the same brief. From the independents, the Borealis Watch Co. Estoril 300 GMT 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.
