Description:
Breitling Chronomat ref 769, a stainless steel chronograph wristwatch, 1940s. Dial: silvered, black sliding rule scale. Calibre: manual winding, 17 jewels. Case: stainless steel round, milled bezel, snap-on back. Case number: 556573. Closure: grey leather strap. Dimensions: 35 mm diameter. Signed: dial and movement. Accessories: none. The dial of the Chronomat tells a lot about its brilliant history. The integrated sliding rule you see here 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.
