Endowed with a look inspired by the 1940s and 1950s and featuring the famous aviation slide rule, the Montbrillant 01 chronograph was named after the building on Ruelle Montbrillant in La Chaux-de-Fonds which housed the Breitling workshops from 1892 to 1979. This successful association of tradition and innovation is enhanced by a silver dial bearing numerals or hour-markers and hollowed counters. The caseback is adorned with an embossed medallion depicting the historical Montbrillant building.
