The Ultimate Athleisure Watch in A Sleek New Size: Breitling’s Endurance Pro Gets A 38 mm Assortment, A Collection-Wide Design Refresh, And A Powered-Up Triathlon Squad

“This is a watch that was built to swim, bike, run, and keep up with you no matter the intensity of your workout—plus, it looks great as a casual sports chronograph,” says Breitling CEO Georges Kern. “This new size makes it accessible to an even wider range of wearers.”

The Endurance Pro is the modern evolution of the Breitling Sprint, introduced in the 1970s as a performance chronograph for the era’s fashion-conscious athletes. Its lightweight resin case and heart-rate-monitoring pulsometer scale made it ideal for sports, the chronograph gave it professional tool-watch status, and its vibrant colors provided the ’70s dayglo cool.

Built for competition, the modern Endurance Pro retains these elements. It’s water-resistant to 10 bar (100 meters) and has a tactile rubberized crown for excellent grip and maneuverability. It can time intervals to 1/10th of a second, take the pulse of an athlete, and keep competitors on the right track with its solar compass. Like the Sprint before it, the Endurance Pro does it all in style and vivid color.
