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?
