Innovative, adventurous and accurate. It's what pilots need in a timepiece and Hamilton always delivers. The Khaki X-Wind features the first ever drift angle calculator to appear in a watch and helps pilots accurately calculate how crosswinds will affect their journey. With a technical look and automatic movement that also suits urban aviators down to the ground it's the perfect everyday co-pilot.
