Breitling Endurance Pro in 44 and 38 mm

Reading Time: 5 minutes

The Breitling Endurance Pro is a multitasking watch that combines the best qualities of the brand’s technical and lifestyle collections. Positioned in the Professional range, it is up to the challenges of a rigorous workout but also serves as a vibrant fashion statement for men and women, making it the ultimate athleisure watch.

The Endurance Pro, previously available exclusively as a 44 mm model, now comes in a universal 38 mm size with five colorful executions. To celebrate the launch, Breitling is welcoming two new members to its Triathlon Squad: reigning IRONMAN® Women’s World Champion Lucy Charles-Barclay and Sam Laidlow, the youngest male winner in IRONMAN history. These exceptional sportspeople join multi-title-holding triathletes Jan Frodeno and Daniela Ryf on Breitling’s crew of pros who know that holding and defending titles demands a watch as tough as their races.

“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.”

Endurance Pro: Revival of the Fittest

With its ultralightweight case and comfortable, form-fitting rubber strap, the Endurance Pro is designed to appeal to committed athletes and casual sports enthusiasts alike. It’s made of Breitlight®, a robust material three times lighter than titanium and nearly six times lighter than stainless steel. The material is also nonmagnetic, thermally stable, hypoallergenic, and highly resistant to scratches, traction, and corrosion.

On the new 38 mm Endurance Pro models, straps and crowns are colored to match the inner bezel rings in a choice of five hues: purple, pink, white, light blue, or red. Meanwhile, the existing 44 mm Breitling Endurance Pro is also getting a refreshed treatment with a new streamlined rubber strap in navy, orange, white, and light-blue colorways. On both sizes, the hands and oversized numerals are coated with Super‑LumiNova® for easy reading in low light.

Like all watches in Breitling’s Professional range, the Endurance Pro is powered by a thermocompensated SuperQuartz™ movement, a technology that is 10 times more accurate than conventional quartz. The 44 mm model contains the Breitling Caliber 82, and the 38 mm size is powered by slightly smaller Caliber 83. Both are COSC-certified chronometers designed to deliver exceptional precision.

Breitling’s Ultralight Watch Heritage

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 Breitling Endurance Pro does it all in style and vivid color.

The Triathlon Squad Gets Two New Members

Breitling’s Professional range of watches are designed to perform in the most extreme conditions and the toughest competitions on Earth. The same can be said for the professional athletes on Breitling’s Triathlon Squad starring in Breitling’s new Endurance Pro campaign.

Meet the members:

JAN FRODENO 

The German Olympic gold medalist, three-time IRONMAN World Champion, and two-time IRONMAN 70.3 World Champion defines what it means to push your limits. He is the first person to win all major triathlon titles for different distances. Throughout his career, Frodeno has broken several world records in the full distance, staying ahead of the competition for 15 years.

DANIELA RYF 

There’s never been a limit to what Daniela Ryf can achieve. Swiss-made like Breitling, Daniela is a five-time IRONMAN World Champion, a five-time IRONMAN 70.3 World Champion, and the current holder of the world record for long-distance triathlon. Her 2018 victories marked the third time that she achieved the prestigious “double”—winning a 70.3 and Kona World Championship in the same year—something that no other triathlete has ever done. 

LUCY CHARLES-BARCLAY 

Lucy Charles-Barclay is redefining endurance sports. This British powerhouse won the 2023 IRONMAN World Championship after finishing as a runner-up four times. She is also an IRONMAN 70.3 World Champion, known for her relentless drive and phenomenal swim prowess. Her determination and tenacity make her a standout in the triathlon world.  

SAM LAIDLOW 

Sam Laidlow showed great potential to become a professional triathlete from a very young age. His relentless training paid off in 2023 when, at just 24 years old, the French athlete became the youngest male winner in the history of the IRONMAN World Championship. Known for his impressive bike splits and fearless racing style, Laidlow is setting new benchmarks and inspiring the next generation of triathletes.
