Breitling Endurance Pro watches

The Breitling Endurance Pro is a lightweight quartz chronograph from Breitling's Professional collection, made for athletes and introduced in 2020. Its 44 mm case, 12.5 mm thick, is made of Breitlight, a material Breitling describes as 3.3 times lighter than titanium and 5.8 times lighter than stainless steel, as well as non-magnetic, hypoallergenic and highly resistant to scratches. The case alone weighs about 35 grams without its strap. It is the second generation of an idea Breitling began with the 2017 Colt Skyracer, a pilot-style watch with a Breitlight case and a three-hand SuperQuartz movement.

Inside is the Breitling Caliber 82, a thermocompensated SuperQuartz chronograph certified by COSC. The chronograph times to 1/10 of a second with a 30-minute counter, and the dial and hands are essentially those of the Aerospace Evo. A bidirectional bezel carries a compass scale, a pulsometer scale lets the wearer take a pulse with the chronograph, and the case is water resistant to 100 m under a sapphire crystal glareproofed on both sides. The lugs take a 22 mm strap that narrows to a 20 mm Breitlight buckle.

The standard models are named for their accent colour, blue, yellow, orange, red or white, which carries through to a coloured rubber strap. The El Paradiso models come in the same five colours. The Ironman Finisher (X823101B1B1S1) has a black and gold dial on a black strap, and the Ironman Red (X823109A1K1S1) a red dial. The Ironman World Championship 2021 edition (E823102A1I1S1) moves to a titanium case with a yellow dial.
