For most watch collectors, when the name "Breitling" is mentioned, the first model that comes to mind is the "Navitimer," the pilot's chronograph and navigational tool that has become synonymous with aviation. However, the success of the "Navitimer" can be attributed to its predecessor, the "Chronomat." While the later "Navitimers" were produced in a 42mm size, the "Chronomat" was built with a sleek 36mm stainless steel case, making it more comfortable and discreet to wear.
In 1941, Breitling applied for a unique watch patent, numbered 217012. This patent was for a watch featuring a rotating slide rule on the bezel. While having a slide rule was not uncommon, Breitling's patent was unique as it combined the slide rule with a chronograph. In 1942, Breitling released the "Chronomat" during the height of World War II. Visually and technically, it differed from the military watches with their simplistic black dials. Instead of being an instrument of war, the "Chronomat" was intended to be an instrument of peace and was marketed as a watch for scientists, engineers, and mathematicians. Its purpose was not to calculate bomb strikes or troop movements but rather to assist in timing and financial calculations. Therefore, as the war came to an end, the watch's advertisements appealed to hard-working individuals who achieved success in the post-war era.
This particular "Chronomat/217012" watch from that era features an absolutely stunning two-tone silvered dial with rich patina and colorful red accents, and the red chronograph hand and blued steel hour and minute hands exhibit rich patina. The movement is equipped with the Venus Cal. 175 manual-winding movement, bearing the Breitling signature, and functions properly.
