The Hamilton Khaki Field Auto 38mm proves you do not need a big watch to get big capability. Rugged, functional and compact, it brings automatic convenience to the classic Khaki Field look, here with a black dial on a leather strap.

Hamilton designed the Khaki Field family as a tribute to the original soldier’s watch, and this model keeps the bold, legible dial that made those watches so useful. What sets the Auto apart is its H-10 automatic caliber: self-winding, with an 80-hour power reserve and a Nivachron balance spring that resists magnetic fields. Turn it over and the open caseback shows the movement working.

At 38mm wide, 11mm thick and 47mm lug to lug, it wears neatly on smaller and medium wrists. The leather strap softens its tool-watch edge for daily wear, while 100m of water resistance and sapphire crystal keep it ready for outdoor plans.
