The short answer
The closest alternative to the Seiko Prospex Sea is the Seiko Prospex Sea PADI Special Edition ($1,200) — shared caliber (Seiko 6R35) and Same family (Prospex Sea). If price is the constraint, the Seiko Prospex Sea PADI Special Edition at $625 (vs $1,500 for the Prospex Sea) covers most of the same brief. From the independents, the Spinnaker Tesei Titanium is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Grand Seiko SBGA481 ($11,100) is where the same idea goes with a bigger budget.
