48 watches that match on case size, movement family, and price band. Sorted by how close the match is.
The closest alternative to the Hamilton Khaki Navy Frogman Auto is the Hamilton Khaki Navy Scuba Auto ($975) — shared caliber (H-10) and Same family (Khaki Navy). If price is the constraint, the Orient Mako-3 AA08 Diver Watch at $375 (vs $1,395 for the Khaki Navy Frogman Auto) covers most of the same brief. From the independents, the Dan Henry 1975 is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Bremont Supermarine 300M ($3,550) 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.
