The short answer

The closest alternative to the Marathon OSAR-D (Original SAR with Date) Automatic 36mm is the Seiko Prospex Sea 1965 Heritage Diver's Watch ($1,300) — common cross-shop and Pro diver. If price is the constraint, the Orient AC0Q-40 Diver Watch at $370 (vs $1,200 for the OSAR-D (Original SAR with Date) Automatic 36mm) covers most of the same brief. From the independents, the Borealis Watch Co. Bull Shark V2 is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Fortis Marinemaster M-40 ($3,520) is where the same idea goes with a bigger budget.
