The Breitling Navitimer Panamerican pilot's watch is a cult classic among aviation enthusiasts. Developed in 1952, it was one of the first pilot's watches capable of undertaking all calculations required for navigation thanks to its unique circular slide rule. Limited to 1,000 watches, the new Breitling Navitimer Panamerican pilot chronograph features a bronze dial with the classic Breitling chronograph tri-compax dial. The bidirectional bezel performs the slide rule that calculates fuel consumption and conversions of mph to km and Celsius to Fahrenheit, to name a few. Visible through the transparent caseback is the in-house calibre 01, a self-winding movement with COSC chronometer certification and 70 hours of power reserve. Water resistant to 30m, the polished steel case measures 43mm and is presented on a Navitimer steel bracelet.
