Celebrating the partnership between the Breitling and legacy British motorcycle company Norton, the Premier B01 Chronograph 42 Norton Edition is a refined and richly detailed timepiece that has heritage written all over its face. It features a 42-millimeter stainless-steel case and transparent caseback to show the workings of the Calibre 01 movement. An engraved Norton nameplate is affixed to the left side of the case.
