The short answer

The closest alternative to the DOXA SUB 300T is the Seiko Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition ($1,400) — common cross-shop and Pro diver. If price is the constraint, the Seiko Prospex Sea PADI Special Edition at $650 (vs $2,190 for the SUB 300T) covers most of the same brief. From the independents, the DOXA SUB 300 is the standout microbrand take — same family (SUB) and Pro diver. Stepping up, the Bremont S502 ($5,100) is where the same idea goes with a bigger budget.
