The short answer

The closest alternative to the Stewart Dawson Royal Marines is the Seiko Prospex Sea 1968 Heritage Diver's GMT ($1,500) — pro diver and Looks nearly identical. If price is the constraint, the Seiko Prospex Sea PADI Special Edition at $650 (vs $1,451 for the Royal Marines) covers most of the same brief. From the independents, the Stewart Dawson Voyager S is the standout microbrand take — shared caliber (Sellita SW200) and Pro diver. Stepping up, the Longines LEGEND DIVER BRONZE ($3,550) is where the same idea goes with a bigger budget.
