The short answer

The closest alternative to the San Martin GR5 Titanium 39mm Sunray Dial Dive SN0121T 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 Spinnaker Spence 300 is the standout microbrand take — common cross-shop and Shared caliber (Seiko NH35). Stepping up, the Yema Superman Gilt CMM.10 ($1,699) is where the same idea goes with a bigger budget.
