The new Khaki Field Mechanical is a faithful recreation of its original 1960s forebear and is true to Hamilton’s military heritage. Inspired by the military, built to last, this is the original soldier’s watch. This Hamilton leather strap is made from natural materials. The leather is tanned, but has not been treated, pigmented and finished in the same way as some other leather straps. This helps it to retain its natural look and also means that every piece is not exactly the same. As a result, the color of the leather strap may differ from the color shown on the image.
