The closest alternative to the San Martin Watchdives x San Martin Classic 39mm Automatic Dive Watch SN0121G is the Orient Kamasu ($375) — common cross-shop and Pro diver. From the independents, the Thorn Watchdives WD007ST 39mm NTTD Dive Watch is the standout microbrand take — shared caliber (Seiko NH35) and Same family (Watchdives). Stepping up, the Christopher Ward C60 Trident Pro 600 ($1,090) 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.
Where the same idea goes when budget isn't the constraint: luxury upgrades and step-ups.
