The short answer

The closest alternative to the San Martin Watchdives x San Martin Upgraded GR5 Titanium 39mm Dive Watch SN0121T-GA is the Invicta Pro Diver 8926T-TF — 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 Zelos Swordfish 40mm Ti is the standout microbrand take — common cross-shop and Shared caliber (Seiko NH35). Stepping up, the Yema Superman Dato CMM.10 ($1,777) is where the same idea goes with a bigger budget.
