The Breitling Endurance Pro is the ultimate athleisure watch: Swiss precision, Ironman spirit and a Breitlight® case six times lighter than steel.
At Maison Roca, we celebrate the fusion between precision engineering and the spirit of endurance. The new Breitling Endurance Pro IRONMAN® embodies that energy: ultra-light, vibrant and designed for those who live in motion. A watch that stands for strength, resilience and freedom.
Lightness and power

The Endurance Pro 44 IRONMAN® is much more than a sports chronograph. Crafted in Breitlight® – an exclusive Breitling material six times lighter than steel – it offers an unparalleled sense of comfort on the wrist. Weighing just 64.9 g, it’s barely perceptible, yet impossible to overlook.
This model blends sporty elegance with extreme performance. Its bold red design evokes the energy and passion of Ironman athletes, while its ergonomic 44 mm architecture ensures a perfect fit for an active lifestyle.
SuperQuartz™ precision


Inside beats the Breitling Caliber 82, a SuperQuartz™ thermocompensated movement that is ten times more accurate than standard quartz. With its 1/10-second chronograph and 30-minute counter, time becomes a true performance tool. Water-resistant to 100 metres, it’s built to follow you from competition to city life.
Pushing limits — with style

The Breitling Endurance Pro IRONMAN® captures the essence of the athleisure spirit: functional, lightweight and effortlessly refined. It’s the perfect companion for those who see life as a constant challenge and wear their determination on their wrist. Whether training, travelling or working, this watch embodies the freedom to push boundaries with elegance.
A collection for those who want more
The Endurance Pro IRONMAN® is part of the Professional line — a collection celebrating human endurance and a passion for adventure. Among its standout editions are the Endurance Pro 44 IRONMAN® World Championship 2025, the 70.3 World Championship 2024 and the exclusive Ibiza Island edition. Each shares the same DNA: ultra-light materials, SuperQuartz™ precision and design inspired by the Ironman spirit. Every model is an invitation to live boldly — with performance, authenticity and style.
