Hamilton Watch Khaki Aviation Pilot Auto H76215130. Crafted for true aviation lovers, the Khaki Pilot Auto evokes the spirit of exploration and adventure of the Khaki. Powered by the H-10 automatic movement with an 80-hour power reserve and Nivachron™ balance spring, the 36mm versions answer the trend for smaller watches. While up to the standards of precision for the cockpit, these more compact designs lend themselves to life in the skies and on terra firma. The Khaki Pilot Auto pairs a timeless stainless-steel bracelet with a stylish black dial and special Super-LumiNova coating for greater readability.
