Breitling launched the Navitimer in 1952, a game-changing watch for pilots. It's a clever chronograph with a built-in "navigator computer" that can handle all the calculations needed for a flight plan. The watch was so popular that it became the official timepiece of the AOPA (Aircraft Owners and Pilots Association), the largest group of pilots in the world. Over the past 50 years, the Navitimer has become a cult classic, joining the ranks of iconic and timeless objects of the 20th century. It's been in production since 1952 with little change in its design and spirit. In fact, it's the oldest chronograph still in production today.Check out the REF
