The Breitling Endurance Pro is a high-performance sport watch from Breitling's Professional collection, designed specifically for endurance athletes and outdoor enthusiasts. Built around the Breitling Light Polylope (BPLP) case—otherwise known as "Breitlight®"—an ultra-light polymer composite—it achieves a remarkably low weight of just 62 g (44 mm version) without sacrificing durability. Powered by the SuperQuartz™ Caliber B82, which is ten times more accurate than standard quartz, the Endurance Pro is a COSC-certified chronometer. Its signature feature is a dedicated countdown timer—ideal for interval training, transitions in triathlon, and pacing during endurance sports. Available in two case sizes (38 mm and 44 mm) and a wide spectrum of bold color options, the Endurance Pro combines precision engineering with an athletic, contemporary aesthetic.

The Endurance Pro is available in two case sizes to suit different wrist sizes and preferences:

• Endurance Pro 38 mm: a more compact option, offering the same technical specification in a lighter, sleeker profile well suited to smaller wrists or those who prefer a discreet fit.

• Endurance Pro 44 mm: the flagship size, providing greater dial legibility and a more assertive sporty presence on the wrist.

Both sizes share the same BPLP polymer case construction, SuperQuartz™ Caliber B82, COSC chronometer certification, pulsometer scale, chronograph functionality that can measure up to 1/10th of a second, and 100 m water resistance. Key references include the X82310 family and multiple limited-edition colorways such as the Ironman® Editions.

The Endurance Pro is powered by the Breitling Caliber B82 SuperQuartz™, a COSC-certified chronometer movement. Unlike a standard quartz caliber, the B82 uses a temperature-compensated oscillator that makes it ten times more precise than conventional quartz — achieving accuracy within ±0.07 seconds per day. This level of precision is particularly useful for athletes that rely on the watch's chronograph functionality.
