The new Breitling Endurance Pro combines an ultra-lightweight 44 mm Breitlight case and a thermocompensated SuperQuartz movement that is ten times more accurate than traditional quartz, offering a level of functionality that is sure to be appreciated by both experienced athletes and "occasional" sportsmen and women. Designed for those who combine an active life with a professional mentality and a sporting lifestyle, the Endurance Pro is up to the challenges posed by rigorous training, but is also suitable for everyday use. As Breitling CEO Georges Kern recalls, "When Jan Frodeno joined our Triathlon Squad, he asked me which Breitling he would wear. We started gathering ideas on the perfect watch for the sporting lifestyle and this conversation led to the development of the Endurance Pro. With this watch, we adapted our SuperQuartz technology to the needs of people like Jan, who work as hard in sport as they do at work. What's more, the Breitlight case is so light that it doesn't interfere in any way with your training routine or sporting activity. The SuperQuartz movement powers all models in Breitling's Professional range. The Endurance Pro introduces the range to the world of sport, in which Breitling has a distinguished tradition. In cycling, the brand has supported major competitions, including the Giro d'Italia and the Tour de France, among others with cycling legends Fausto Coppi and Gino Bartali. The same applies to motor sports, where Breitling has sponsored famous rallies. The Endurance Pro is inspired by the Breitling Sprint, a watch from the 1970s that combined a pulsometer with a very low weight. The Endurance Pro models feature a black dial and a matching bidirectional rotating bezel engraved with the cardinal points. There are five variants of the new Breitling Endurance Pro, all distinguished by their bright colours: the bezel is available in white, blue, yellow, orange or red, and all are marked with the pulse-rate scale so that the user can keep track of his or her heart rate during sporting sessions. The watch is also equipped with a 1/10th of a second chronograph. The strap is made of Diver Pro rubber in the same colour as the inner bezel (white, blue, yellow, orange or red; NATO Outerknown straps in ECONYL thread can be purchased separately) and is closed by a Breitlight double pin buckle. At the heart of the Endurance Pro is the COSC-certified Breitling 82 calibre, whose SuperQuartz technology guarantees excellent precision. Finally, the Breitling Endurance Pro is water-resistant to 10 atmospheres and comes with a two-year warranty.
