Built around Breitling's exclusive black matt Ultralight Polymer Breitlight, the 44mm Endurance PRO case is matched to a red rubber Diver Pro strap secured by a tang buckle clasp. A sapphire crystal, glare-proofed on both sides, protects the black dial, which features applied polished large Arabic numerals at 3, 6, and 9 o'clock alongside smaller luminous painted Arabic numerals at the remaining hour positions. A white-outlined minute and seconds track runs along the dial perimeter, while the crown and chronograph pushers carry coordinating red accents.
The dial layout is purpose-driven: a date window sits between 4 and 5 o'clock, a small seconds sub-dial occupies 6 o'clock, a 1/10-second counter sub-dial appears at 2–3 o'clock, and a 30-minute counter sub-dial is positioned at 9–10 o'clock. A large red central seconds counter hand commands the chronograph display. The bidirectional bezel is engraved with a compass scale, and water resistance reaches 100m/330ft.
Power comes from the COSC-certified Breitling Thermocompensated SuperQuartz caliber 82, delivering precision well beyond standard quartz benchmarks. Reference X82310D91B1S1 is presented with its original Breitling watch box and Breitling papers, and carries a Breitling warranty.
