The Endurance Pro was designed for elite triathletes, but works just as well as a stylish sports chronograph for everyday wear. With its rubber strap and 100 m water resistance, the Endurance Pro IRONMAN performs just as well in water as it does on land. And each one is powered by Breitling’s Caliber 82, a COSC-certified SuperQuartzTM movement that delivers exceptional accuracy. Combine that with its easy readability, chronograph function and solar compass, and you have a powerful motivator for crossing the finish line
