The Khaki Field H70315931, seen from the bench

The Hamilton Khaki Field H70315931 is a contemporary evolution of military aviation watches from 1940. This stainless steel case measures 41 mm with a brushed finish and matte dial offering full readability. The H-10 ND caliber provides manual wind movement at 28,800 vph. The 20 mm lug width is integral to the visual balance between case diameter and lateral proportion. Built from 316L stainless steel for superior corrosion resistance, this instrument watch exemplifies functional design without compromise.
