The Navitimer Chronograph GMT 46, with its black dial and effortlessly legible dual timezone system, is designed for the modern traveler. A red-tipped additional central hand can display the time (on a 24-hour scale) at any destination and the caseback is engraved with the time zones of the world's major cities. The self-winding chronograph movement is housed in the 46mm case, which has a bidirectional rotating bezel and Breitling's iconic circular slide rule for onboard calculations. Powered by a self-winding Breitling 24 caliber, this sophisticated tool watch is presented on a black alligator or leather strap, or Navitimer stainless steel bracelet.
