Featuring a look inspired by the 1940s and 1950s and the famous circular slide rule for aviators, the Montbrillant chronograph was named in tribute to the building on Montbrillant Street, in the heights of La Chaux-de-Fonds, which housed the Breitling workshops from 1892 to 1979. It was in these premises that the brand devised the inventions and the technical developments that were to change the face of the wrist chronograph, including the first independent pushpiece (1915), the second independent pushpiece (1934) and the first selfwinding chronograph (1969). It was also under this roof that Breitling produced the famous onboard chronographs that earned it the status of “official supplier to world aviation” during the boom in propeller-driven and later jet-powered air transport. Today, the Montbrillant spirit continues to pervade a collection of chronographs endowed with aesthetic details paying homage to the grand tradition, including slender hands, a central hundredth of an hour indication and a stylized B in 18-carat gold.
