38 mm stainless steel case, three hand display, dark dial with light-colored numerals, triangular indexes with old radium color Super-LumiNova, durable NATO strap: The new Khaki Field Mechanical is a faithful recreation of its original 1960s forebear and is true to Hamilton military heritage. The original soldierwatch now features Hamilton unique Earth colored PVD case coating. 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.
