The short answer

The closest alternative to the Seiko Prospex Sea PADI Special Edition is the Seiko Prospex Sea ($625) — shared caliber (Seiko 4R35) and Same family (Prospex Sea). If price is the constraint, the Orient Diver Watch at $285 (vs $625 for the Prospex Sea PADI Special Edition) covers most of the same brief. From the independents, the Spinnaker Hass Automatic is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Seiko Prospex Sea ($1,500) is where the same idea goes with a bigger budget.
