Soon after its launch in 1952, the NAVITIMER chronograph became a favorite with pilots. In addition to its ability to measure short times, this wrist instrument is equipped with a "navigation 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.

Intended for professionals, TAG Heuer’s Specialists models reflect more than 140 years of expertise. The Pilot chronograph provides the essential calculations for navigation by land, sea and air. Cut from a single block of steel, water-resistant to 1000 meters, equipped with a screw-in crown and unidirectional turning bezel with large ratchet, the 1000 M is designed to withstand extreme depths. The Searacer chronograph, developed with professional sailors who include Chris Dickson and Pierre Fehlmann, offers totally new functions : the countdown ''Regatta'' (10, 6 or 5 minutes), the restart function and the 1/10th chronograph function. Stretching beyond one''s limits. The TAG Heuer image has always been closely associated with that of high-level competition.
