The Montbrillant 01 chronograph is a nod to the classic Chronomat watches from the 1940s and 1950s, complete with the iconic aviation slide rule. It's named after the old Breitling workshops in La Chaux-de-Fonds, where it all began. It runs on the impressive Manufacture Breitling Caliber 01. The dial has either numerals or hour markers, with cutout subdials. The caseback features a special medallion depicting the historic Montbrillant building. The red gold case and Mercury Silver dial with stick markers make the Reference RB013012.G710 a standout choice.
