Hamilton Khaki Field King Day-Date Auto 40mm Green

The 40mm stainless steel case carries the bead-blasted top surface and brushed flanks that signal the watch's tool-watch heritage, with crown guards integrated into the case profile. A sapphire crystal with anti-reflective treatment protects the dial, and water resistance is rated to 100 metres.

The dial is finished in a sun-brushed khaki green — deeper than military olive and lighter than racing — with bold Arabic numerals, an inner 24-hour military scale and luminous syringe-style hands. The day-date display sits in a curved aperture at twelve o'clock, the wide window now a defining cue of the King line.

Calibre H-40 is Hamilton's automatic chronometer-grade movement, fitted with a Nivachron anti-magnetic balance spring and delivering 80 hours of power reserve.

Mounted on a brown calf leather strap with contrast white stitching and stainless steel pin buckle.
