In launching the Navitimer in 1952, Breitling gave pilots a genuine wrist instrument. Ingenious and efficient, this chronograph is endowed with a built-in “navigator computer”, a circular slide rule capable of performing all calculations a flight plan requires. The Navitimer thus became the official watch of the AOPA (Aircraft Owners and Pilots Association), the world’s largest grouping of pilots. In its fifty years of existence, the Navitimer has achieved cult object status, thereby joining the select circle of modern, ultra-functional and timeless objects that have made their mark on the 20th century. Since the famous “806” model in 1952, the Navitimer has found its way through the years unchanged in either form and spirit. Continuously produced throughout this period, it is now the world’s oldest chronograph.
