About the Hamilton Khaki Field Auto 42mm Automatic Men's Watch, Black Dial, Brown Leather Strap (H70555533)

The Hamilton Khaki Field Auto (reference H70555533) is a 42mm automatic field watch inspired by the watches Hamilton made for soldiers. A black dial with bold white Arabic numerals and a brown leather strap give it a rugged, easy-to-read look that works as well in the city as it does outdoors.

Inside is Hamilton's H-10 automatic movement with up to 80 hours of power reserve, so it keeps running through a weekend off the wrist. Its Nivachron balance spring is designed to reduce the effects of magnetism, temperature changes and shocks on timekeeping, and the open caseback lets you see the movement at work.

The stainless steel case measures 42mm across and about 11mm thick, with 22mm lugs and a 53mm lug-to-lug length. A scratch-resistant sapphire crystal protects the dial, Super-LumiNova helps you read the time in low light, and a date window adds everyday convenience. Water resistance is 100 meters (10 bar).

The brown cow leather strap closes with a classic pin buckle. Hamilton notes that this model was featured in The Avengers (2012), worn by Steve Rogers.

What reviewers say

Owner reviews on Hamilton's US site average 4.8 out of 5 from 73 ratings. Owners describe a classic, timeless look, solid construction and a comfortable fit, and several mention getting compliments; one praises the snappy date change and the bright polish on parts of the case. The main complaint was a leather strap that felt too short and less premium than the watch. Fratello's long-term owner review of the 38mm Khaki Field Auto (same H-10 movement and design family) says it still holds up after more than a decade in the catalog, praising the sapphire crystal and 80-hour reserve and saying it never felt out of place, from outdoor trips to dinner out. It notes some people dislike the polished bezel, and several Fratello readers mention noticeable glare on the crystal.

Pros

  • Classic, timeless field-watch look that owners say draws compliments
  • 80-hour power reserve from the H-10 movement
  • Solid build with a sapphire crystal
  • Comfortable for everyday wear
  • Versatile enough for outdoor trips or a dinner out (Fratello)

Cons

  • One owner found the leather strap short and less premium than the watch
  • Some owners report noticeable glare on the crystal
  • The polished bezel is not to every field-watch fan's taste
