Endurance Pro 44 IRONMAN® 70. 3 World Championship 2024Breitling's IRONMAN® 70. 3 World Championship edition ultra-lightweight Endurance Pro watch. On your toughest stretches and your steepest climbs, what drives you to push to the finish? You have the mental ammunition to keep you going. Let your Endurance Pro IRONMAN® edition be another tool in your arsenal. The Endurance pro was designed for elite triathletes but works just as well as a stylish sports chronograph for everyday wear. It's made of Breitlight®, a robust material 3. 3 times lighter than titanium and 5. 8 times lighter than stainless steel. It's also thermally stable ( with a touch that's warmer than metal), while being scratch-resistant, non-magnetic and hypo-allergenic. With its rubber strap and 100m 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 Super Quartz movement that provides exceptional accuracy. C
