In 1969, Breitling presented the first selfwinding chronograph movement, an innovation that paved the way for the development of a whole range of chronographs with an avant-garde look named Chrono-Matic. The contemporary 49 mm-diameter Chrono-Matic pays fine tribute to this pioneer of ultra-large size watches that has become an icon of 20th century watch design. A descendant of the Navitimer lineage, as confirmed by its slide rule, it is distinguished by its modern design featuring sixties and seventies accents epitomized by a case with taut, angular lines. The rectilinear hands, the design of the counters and the choice of wristbands are all nods to the aesthetic styling of the era. The dial bears the brand logo used between the 1950s and 1970s, with the Breitling signature topped by a gold version of the initial B. The rotating pinion bezel driving the aviation slide rule is made from rubber-molded steel.
