The short answer

The closest alternative to the San Martin Watchdives X Upgraded GR5 Titanium 39mm ST2130 Di is the Orient Kamasu ($375) — common cross-shop and Pro diver. If price is the constraint, the Casio Edifice EFK-100D covers most of the same brief. From the independents, the Militado 39mm Dive Watch PT5000 Automatic Mech Watch ML20 is the standout microbrand take — shared caliber (PT5000) and Pro diver. Stepping up, the Tissot Seastar 1000 ($875) is where the same idea goes with a bigger budget.
