Breitling - With a passion for precision, Leon Breitling made a name for himself by creating industrial counters and high quality instruments to measure brief time intervals. The year was 1884, the place was Saint-Imier, Switzerland, and the result has been a series of Breitling watches that many of the world’s best pilots rely on. From the renowned Navitimer collection to the Windrider and Professional, Breitling is a must-have brand in the world of aviation. In fact, many of its watches come equipped with a circular slide rule, on which most flight calculations can be performed.
