38 watches that match on case size, movement family, and price band. Sorted by how close the match is.
The closest alternative to the STEELDIVE SD1946S is the Glycine Men's Combat Sub Bronze 42mm Automatic Watch GL0390 ($615) — common cross-shop and Pro diver. If price is the constraint, the Orient FNR1Q003W0 at $155 (vs $328 for the SD1946S) covers most of the same brief. From the independents, the Zelos Hammerhead 1000m Diver Black with Ceramic Bezel is the standout microbrand take — common cross-shop and Shared caliber (Seiko NH35). Stepping up, the Glycine Men's Combat Sub Sport GMT Bronze 42mm Automatic Watch GL0316 ($2,995) 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.
