Features automatic winding via tungsten alloy micro-rotor, hours and minutes display, and flying tourbillon at 6 o'clock with the stylised '&' of Bell & Ross integrated into the cage. Movement thickness of just 4.05mm allows for the unique case construction where the movement is sandwiched between two sapphire crystals. Developed by MHC (Manufacture Haute Complication) in Geneva.
