39 watches that match on case size, movement family, and price band. Sorted by how close the match is.
The closest alternative to the San Martin New Upgrade GMT Men Watch SN0129G-3 is the Orient AC0Q-40 Diver Watch ($370) — 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 Charlie Paris Watches CONCORDIA - GMT (40mm automatic) is the standout microbrand take — shared caliber (Seiko NH34) and Pro diver. Stepping up, the Glycine Men's Airman Vintage The Chief GMT 40mm Automatic Watch GL0303 ($600) is where the same idea goes with a bigger budget.
Independent makers covering the same brief, usually with something the mainstream brands don't.
Established brands covering the same brief at a comparable price: same case size, similar movement family. Often the deciding click for a new buyer.
If the price is the only thing keeping you off this watch, these get you most of the way there for less.
Where the same idea goes when budget isn't the constraint: luxury upgrades and step-ups.
