Not all watch brand sponsorships are perfect fits. But when Breitling became the official luxury watch partner of the Ironman triathlon in 2021, I just nodded my head.
“Yep. That makes sense.”
Four years on, Breitling continues to celebrate its partnership with one of the world’s most grueling athletic events with a new limited-edition chronograph that takes what is already one of the toughest watches in the business and makes it even more durable.
I am Ironman
Breitling’s new Ironman watch is the — deep breath — Professional Endurance Pro Ironman World Championship 2025. Mouthful of a name aside, this is effectively a ruggedized version of Breitling’s already formidable Endurance Pro chronograph, with a couple of extra touches aimed at Ironman athletes.

Powering the watch, as always, is Breitling’s Cal. 82 quartz chronograph movement. Now, before you roll your eyes, you must realize this is no ordinary quartz movement.
