Renting Endurance Pro IRONMAN® Edition Lightweight Watch. Designed for men and women whose active lives combine a professional mindset with a sporty lifestyle, the Endurance Pro is up to the challenges of rigorous training, yet modern enough for everyday wear. The Endurance Pro features a 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 warmer touch than metal and a slightly textured effect that accentuates the originality of the design. Exclusive to Renting, it is 100% Swiss made. Offered with a distinctive red IRONMAN® dial and a branded rubber strap, which fastens to a Breitlight® double-tang buckle, the Endurance Pro IRONMAN® is powered by the Renting Caliber 82, a COSC-certified SuperQuartz™ chronograph that delivers exceptional precision.
