The original soldier's watch gets an original upgrade with Hamilton's first-ever bronze case. Each Khaki Field Mechanical Bronze has a unique story that will unfold with each wear as its case develops a distinct patina over time. Powered by our exclusive hand-wound H-50 movement, fitted to a titanium case back and matched with a soft brown leather NATO strap, this authentic 38mm favorite celebrates Hamilton's military heritage with an eye towards the future. What story will your field watch tell?

Loving this watch. Easy use, sturdy, and clean looking. The leather strap is very nice. I want wait to see patina it develops over time.

I bought this watch for my wedding day. It made a lovely accent to an exceptional day. I love the manual action, leather strap, and bronze face.

Great watch. Good size for a slightly smaller than average wrist, The case is great, strap is high quality an it feels light on the wrist. Absolutely no complaints. I keep looking at other watch brands at this price point and always end up coming back to Hamilton.

I was deciding between an Apple Watch and this one, but nowadays almost all my colleagues have an Apple Watch, and it still doesn't replace a phone. So I will always have to carry my phone. Then I chose this watch—Swiss made, one with character, history, beauty, one that no one else has.

Gorgeous watch, light weight, keeps perfect time. I have received multiple compliments. Very excited to work in a patina to really drive the vintage look home

The only issue I have had is the surcharge for a bronze case, I think it is steep. Though still purchased it so I guess I can’t complain to much
