San Martin San Martin Watchdives X Upgraded GR5 Titanium 39mm ST2130 Di

The San Martin Watchdives X Upgraded GR5 Titanium 39mm ST2130 Di is praised for its Grade 5 titanium case, on-the-fly adjustable clasp, and smooth second-hand sweep from the ST2130 movement, with owners noting its thin 11.5mm profile and versatility across casual and formal wear. The $15–20 price increase for the Grade 5 case upgrade over the previous generation is considered fair, though the bracelet and clasp remain Grade 2 titanium, limiting the practical impact of the material change; one earlier owner noted titanium scratches similarly across grades due to the soft oxide patina, though Grade 5 is acknowledged as harder to machine and likely more scratch-resistant. Overall, the San Martin Watchdives X Upgraded GR5 Titanium is valued for its lightweight titanium construction and refined finishing at a competitive price point.
