The Breitling Navitimer Super 8 was inspired by the reference number 637, a stopwatch that Second World War bomber pilots wore strapped to their thighs. The bold new wrist watch features a 46 mm case available in titanium or stainless steel and is presented on a brown NATO leather strap. With its signature bidirectional rotating bezel, the Navitimer Super 8 has an overall diameter of 50 mm. Thanks to the prominent screw-locked crown positioned on the right side of the case, the watch offers exceptional comfort to wearers in spite of its impressive dimensions. Its large Arabic numerals and its hour and minute hands are luminescent, making the Navitimer Super 8 easy to read in all lighting conditions. An ingenious and practical triangular pointer is adjusted by rotating the bezel, making it particularly easy to track elapsed times. At the heart of this COSC-certified chronometer is the Manufacture Caliber B20, based on the Tudor Caliber MT5612, which delivers a power reserve of over 70 hours.
