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 Field Day Date Auto is the Hamilton Khaki Field Day Date Auto ($895) — shared caliber (Hamilton H-30) and Same family (Khaki Field). If price is the constraint, the Glycine Men's Combat Field 42mm Automatic Watch GL0559 at $380 covers most of the same brief. From the independents, the Praesidus Service Watch is the standout microbrand take — common cross-shop and Field watch.
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.
