Hamilton Khaki Field Auto 38mm

About This Watch

The Hamilton Khaki Field Auto 38mm on bracelet is the automatic counterpart to the beloved hand-wound Mechanical, adding the convenience of self-winding and a date complication while retaining the military DNA that defines the Khaki Field collection. The H-10 caliber inside is based on the ETA 2824-2 but modified by Hamilton to deliver an extraordinary 80-hour power reserve by reducing the beat rate to 21,600 vibrations per hour. This means the watch can sit unworn from Friday evening to Monday morning and still be running when you pick it up — a genuinely useful feature for those who rotate between multiple watches. The 38mm case wears true to size on the wrist, its brushed surfaces and angular lugs giving it a purposeful, tool-watch aesthetic that works equally well with field gear and office attire. The stainless steel bracelet elevates the watch beyond its military roots, featuring a comfortable three-link design with brushed center links and polished outer links. The black dial maintains the classic Khaki Field layout with Arabic numerals, a date window at 3 o'clock, and excellent luminous treatment. At 100 meters of water resistance, it handles everything short of actual diving. The Khaki Field Auto 38mm on bracelet represents the practical sweet spot in Hamilton's lineup — automatic convenience, bracelet refinement, and military heritage at a price that makes Swiss mechanical watchmaking genuinely accessible to everyone.
