Breitling’s IRONMAN® edition lightweight Endurance Pro watch. Designed for men and women whose active lives blend a professional mindset with a sporty lifestyle, the Endurance Pro is equal to the challenges of a rigorous workout but fashionable enough for everyday wear. The Endurance Pro features an ultra-light Breitlight® case, a robust material 3.3 times lighter than titanium and 5.8 times lighter than stainless steel. Non-magnetic, thermally stable and hypoallergenic, Breitlight® is highly resistant to scratches, traction and corrosion. It also has a touch that is warmer than metal and a slightly textured effect accentuating the originality of the design. Exclusive to Breitling, it is 100% Swiss-made. Offered with a distinctive IRONMAN® red dial and branded rubber strap – fitting a Breitlight® double tang-type buckle, the Endurance Pro IRONMAN® is powered by the Breitling Caliber 82, a COSC-certified SuperQuartz™ chronograph delivering exceptional precision.
