The 45 mm version of the super-charged Breitling, this selfwinding chronograph houses a high-performance Manufacture Breitling Caliber 01 in an ultra-sturdy, ultra-light case in Breitlight: an avant-garde alloy used for the first time in the watch industry. Its original, technical and powerful look is accentuated by a black or yellow dial with aviation-inspired white stencil-type numerals, as well as an exclusive strap combining rubber and high-resistance Military textile fiber. An instrument built for extremes.
