Hamilton's prestigious history of serving the flying community means our collection represents developments in aviation watchmaking over time. The Khaki Pilot Pioneer range is a nod to 70s military aviation design but relies on modern technology to make it tick. The Auto Chrono is powered by the latest H-31 chronograph movement, with a power reserve of up to 60 hours. Modern materials meet tried and tested design for an impressive display.
The H-31 is a powerful automatic chronograph movement featuring an extended 60-hour power reserve, making it perfect for the demands of the sportiest of models. With an H pattern design on the oscillating bridge, there’s no mistaking who made this movement.
