The integrated sliding rule was patented (patent no. 217012, as seen on the dial) in 1942. This innovation not only performed as a tachometer and pulsometer, but also allowed the wearer to compute elementary operations such as multiplication and division. The Chronomat was obviously a very meaningful watch for Breitling, but its historical significance extends far beyond the context of the brand; it can be considered the smartwatch of its time. This watch is also an ancestor of the Navitimer, which would extend the same principles to the world of aviation a decade later.

This Chronomat is extremely legible, and highly useful if you know how to operate a slide rule. The dauphine handset got the nice bluish look and have aged wonderfully. The silver dial got the characteristic design of the 1950s, with the applied logo and Genève line. The dial have some signs of aging otherwise its condition is spectacular for a 70-year old watch. The stainless steel case also shows some superficial scratches on the case bands, but its lugs have been well preserved.
