The short answer
The closest alternative to the Seiko Prospex Sea is the Seiko Prospex Sea PADI Special Edition ($650) — shared caliber (Seiko 4R35) and Same family (Prospex Sea). If price is the constraint, the Orient AA02 Diver Watch at $285 (vs $595 for the Prospex Sea) covers most of the same brief. From the independents, the Zelos Blacktip 41 is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Seiko Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition ($1,750) is where the same idea goes with a bigger budget.
