The short answer

The closest alternative to the San Martin Watchdives x San Martin Classic 39mm Automatic Dive Watch SN0121GA is the Invicta Pro Diver 8927OB — shared caliber (Seiko NH35) and Pro diver. If price is the constraint, the Seiko Conceptual SNK807K2 at $115 (vs $238 for the Watchdives x San Martin Classic 39mm Automatic Dive Watch SN0121GA) covers most of the same brief. From the independents, the Thorn Watchdives WD007ST 39mm NTTD Dive Watch is the standout microbrand take — shared caliber (Seiko NH35) and Same family (Watchdives). Stepping up, the Glycine Unisex Combat Sub Bronze 39mm Automatic Watch GL0517 ($1,550) is where the same idea goes with a bigger budget.
