One of the most famous models of BreitlingThe Montbrillant chronograph, named in memory of the little street in Montbrillant, on the heights of La Chaux-de-Fonds, which housed the company's workshops from 1892 to 1979. Today, the success of this timepiece is due to the movement that equips it, Breitling Calibre 01, chronometer-certified by the COSC and visible through the sapphire crystal opening in the caseback. The case, in a limited edition of 2,000 for the steel version and 200 for the 18-carat red gold version, surrounds a Mercury silver dial on which appears, at 12 o'clock, the famous stylised gold 'B', the brand's symbol until the mid-20th century. The watch comes with a Barenia or crocodile leather strap, or an Air Racer or Navitimer bracelet (in steel only).
