The short answer

The closest alternative to the San Martin Watchdives x San Martin Upgraded GR5 Titanium 39mm NH35/PT5000/ST2130 Dive Watch SN0121TD is the Invicta Pro Diver 5053 — shared caliber (Seiko NH35) and Pro diver. If price is the constraint, the Casio Edifice EFK-100D 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 Seiko Prospex Sea 1965 Heritage Diver's Watch ($1,300) is where the same idea goes with a bigger budget.
