Breitling has long been associated with IRONMAN®—the brand became the official luxury watch partner of the endurance race in 2021 with the launch of two limited-edition Endurance Pro IRONMAN watches.

‍

‍

Strengthening the partnership, Breitling has unveiled two new limited editions of its endurance-focused sports chronograph—the Endurance Pro IRONMAN World Championship® 2025 Edition in titanium, and the Endurance Pro IRONMAN® 70.3® World Championship 2025 Edition in Breitlight®. These models mark the upcoming triathlon competitions: the IRONMAN World Championship® in Nice, France (September 14, 2025, men’s race) and Kailua-Kona, Hawaii (October 11, 2025, women’s race), as well as the IRONMAN® 70.3® World Championship in Marbella, Spain (November 8–9, 2025).

‍

Both timepieces are housed in 44 mm cases with a 12.5 mm thickness and a lug-to-lug span of 52.49 mm, designed for comfort and resilience during competition. Water resistance is rated to 100 metres, with a non-screw-locked crown with dual gaskets, and a flat sapphire crystal glareproofed on both sides. The construction includes a bidirectional bezel with a compass scale, enhancing its role as a tool watch.

‍

The first timepiece, Endurance Pro IRONMAN World Championship 2025 Edition (Ref. E823105A1M1S1), is limited to 500 pieces. Crafted in titanium, it is both lightweight and robust. The titanium-grey dial carries a blue and light-blue inner bezel with a pulsometer scale, black chronograph subdials, and the special IRONMAN World Championship logo at 6 o’clock, depicting an eagle and turtle—symbols of Nice and Hawaii. Numerals and hands coated with Super-LumiNova® ensure visibility in low-light conditions. The model is fitted with a blue IRONMAN-branded rubber strap with a stainless-steel double tang buckle.

‍

The second, Endurance Pro IRONMAN 70.3 World Championship 2025 Edition (Ref. X823101K1C1S1), is limited to 300 pieces and crafted in Breitlight®—Breitling’s proprietary polymer composite that is 3.3 times lighter than titanium and 5.8 times lighter than stainless steel. The material is hypoallergenic, scratch-resistant, and thermally stable. Its turquoise dial is matched with a turquoise inner bezel bearing a pulsometer scale, black chronograph counters, and the IRONMAN 70.3 World Championship Marbella logo at 6 o’clock, inspired by Andalusian architectural motifs and natural surroundings. A turquoise IRONMAN-branded rubber strap with a Breitlight® double tang buckle completes the timepiece.

‍

‍

Both models are powered by the Breitling Caliber 82, a COSC-certified thermocompensated SuperQuartz™ movement that is ten times more accurate than standard quartz. Functions include chronograph timing to 1/10th of a second, a 30-minute counter, and a date display. Power is supplied by a long-life battery lasting approximately two years.

‍

The Endurance Pro IRONMAN World Championship 2025 Edition is available now, while the IRONMAN 70.3 World Championship 2025 Edition will launch in October 2025. Both references will be sold exclusively at the brand’s website, select boutiques and retailers, and at race venues in Nice and Marbella.
