Soon after its launch in 1952, the NAVITIMER womanplatinumrings chronograph became a favorite with pilots. In addition to its ability to measure short times, this wrist instrument is equipped with a "navigation womanplatinumrings computer", a circular slide rule able to handle all airborne navigation calculations, such as climbing times or fuel consumption rate, and even to convert miles into nautical miles or kilometers. This first NAVITIMER was officially chosen by the AOPA (Aircraft Owners and Pilots Association), encompassing pilots from around the world. Today, this model has lent its name to a line of original mechanical chronographs, featuring a wealth of exclusive technical features and naturally all fitted with the famous slide rule. The PROFESSIONAL line encompasses the BREITLING chronographs most specifically tailored to the world of aviation. From the EMERGENCY built-in microtransmitter to the electronic sophistication of the B-1, along with the ease of handling typical of AEROSPACE models, BREITLING places its finest technology in the service of pilots.
