The Montbrillant 01 chronograph from Breitling pays homage to the classic design of early Chronomat watches from the 1940s and 1950s. It even includes the iconic aviation slide rule. The name comes from the building in La Chaux-de-Fonds where Breitling was based for almost 90 years. This watch is powered by the impressive Manufacture Breitling Caliber 01. The combination of tradition and innovation is highlighted by a dial with either numerals or hour markers and hollowed counters. The back of the watch features a special medallion depicting the historic Montbrillant building. The Reference RB013012.G736 version has a luxurious red gold case and a Mercury Silver dial
