The Hamilton Khaki line comprises the Hamilton military watches with their long and strong tradition. "Khaki" originates from the Hindu word for earth or dust and has long been the color used for military uniforms. Today the color is associated with adventure, and the current Khaki watches in the Hamilton collection are direct descendents of their heroic forerunners that served the armed forces in both world wars. Within the Hamilton Khaki line there are four families: Aviation, Action, Field and Navy, all with individual identities characterized by different functions, cases, colors, strap materials and hand or dial designs.
