The Montbrillant 01 chronograph pays homage to the early Chronomat watches from the 1940s and 1950s. Its design includes the iconic aviation slide rule and is named after the building in La Chaux-de-Fonds where Breitling used to have their workshops. The watch is powered by the impressive Manufacture Breitling Caliber 01 and is a perfect blend of tradition and innovation. The dial comes in either numerals or hour-markers with counters that are hollowed out. The caseback features a special medallion depicting the historic Montbrillant building. The reference AB013012.G735 has a stainless steel case and a Mercury Silver dial with elegant Breguet numerals.
