The Montbrillant 01 chronograph pays homage to the early Chronomat models from the 1940s and 1950s, complete with the iconic aviation slide rule. It's named after the Breitling workshops on Ruelle Montbrillant, where they were based for almost a century. The watch boasts the top-performing Manufacture Breitling Caliber 01 and combines classic and modern elements. The dial comes with either numerals or hour markers and hollowed counters, while the caseback features a medallion depicting the historic Montbrillant building. The stainless steel AB013012.G735 model has a striking Mercury Silver dial with elegant Breguet numerals.
