In 1952, Breitling created a “wrist instrument†specially designed for pilots and other aeronautical professionals. Equipped with a circular slide rule, the famous Navitimer chronograph serves to handle all calculations linked to airborne navigation: average speed, distance covered, fuel consumption, rate of climb or descent, conversions from miles to kilometers or nautical miles, etc. Accurate, ingenious and efficient, the Navitimer was soon chosen as the official watch of the AOPA (Aircraft Owners and Pilots Association), the world’s largest association of its kind. With its original and elegant high-tech look, this unique instrument has asserted itself as the most iconic Breitling model – and a cult object for all aviation enthusiasts. Continuously made for almost sixty years, this legendary watch is also the world’s oldest mechanical chronograph still in production.
