Breitling Endurance Pro

With their colorful straps, Breitlight cases, and precise SuperQuartz calibers, Endurance Pro chronographs are truly state of the art. Their bright rubber straps are available in red, yellow, orange, green, blue, black, and white. Together with a matching ring around the dial's edge, the straps add a stylish, youthful touch to these otherwise black timepieces. Breitling also offers versions on colorful NATO straps.

The Triathlon series is home to aptly named Endurance Pro "Ironman" models. The most popular model features a red dial and comes on a red rubber strap. All the other models have black dials.

Another highlight is the case, which Breitling crafts out of a proprietary material called Breitlight. According to the manufacturer, this polymer is 3.3 times lighter than titanium and 5.8 times lighter than stainless steel. What's more, it is anti-magnetic, hypoallergenic, highly resistant to corrosion and scratches, and has exceptional tensile strength. The case is water-resistant to 100 m (10 bar, 328 ft), meaning it can join you for a swim. In fact, the Endurance Pro is the timepiece of choice for professional triathletes and Breitling brand ambassadors Jan Frodeno, Daniela Ryf, and Chris "Macca" McCormack.

The SuperQuartz caliber B82 ticks away inside the Breitling Endurance Pro. This thermo-compensated movement boasts chronometer certification from the Official Swiss Chronometer Testing Institute (COSC), meaning it is extremely precise. A quartz chronometer movement may not deviate from the reference time by more than +/- 25 seconds per year. Standards for mechanical movements are much lower.

Prices for Breitling Endurance Pro models vary slightly based on the strap color. The standard version on a red rubber strap can be yours for around 2,700 USD. The other watches in the collection cost between 2,800 and 9,700 USD. The Endurance Pro Ironman, which is also paired with a red strap, costs about 3,100 USD in mint condition.

The Breitling Endurance Pro immediately catches the eye with its colorful strap options. The ring around the dial's edge, indices, crown ribbing, and ring in the upper push-piece shine in a matching hue. The outer dial ring also features a pulsometer for measuring the wearer's pulse.

Large Arabic numerals filled with luminous material mark the hours, with the 3, 6, and 9 being nearly twice the size of the other numerals. The hands also glow in the dark, thus guaranteeing optimal readability in all lighting conditions. The model name appears below the 9, while the word "Chronometer" sits just below the 3. The Breitling logo sits at 12 o'clock.

The subdials at 2, 6, and 10 o'clock serve as an hour counter, small seconds, and minute counter, respectively. Thanks to the Endurance Pro's SuperQuartz caliber, you can measure periods of time up to 12 hours to within 1/10th of a second. A date display at 4:30 completes the dial.

The Breitlight case is 44 mm in diameter and 12.5 mm thick; its lugs have a width of 22 mm. Scratch-resistant, anti-reflective sapphire crystal protects the displays against the elements. The bezel rotates in both directions and comes with a compass rose for assisting with navigation. Breitling also crafts the case back out of Breitlight and holds it in place with four screws.
