Hamilton has a proud military heritage, one that's immediately apparent with its Khaki Field model. This particular reference, H70205830, combines an H-10 automatic movement with an 80-hour power reserve and a 38mm titanium case for lightweight utility. A black dial contrasts with lume-filled Arabic numerals and hour/minute hands and is also outfitted with an orange-tipped seconds hand, 24-hour, and 60-minute markings. It's finished with a crystal caseback and grey calf leather strap.
