Hamilton Watch Khaki Aviation Pilot Pioneer Chrono Quartz H76522931. The Khaki Pilot Pioneer Chrono Quartz is inspired by the traditional military aviation watches from the 70s, specifically the model that Hamilton designed for the Royal Air Force. The Superluminova hands make the dial on the Pilot Pioneer perfectly readable and the Nato strap is reminiscent of the military roots of the Pilot Pioneers ancestor. The two asymmetric counters and case propel the watch in the modern time.
