The Endurance Pro X82310281B1S1, seen from the bench

The Endurance Pro Blue is a 44mm sports chronograph by Breitling launched in 2020, featuring the Breitling 82 COSC-certified movement with chronograph, small seconds, minute counter, and foudroyante seconds. The case combines Titaplast—a proprietary composite of carbon fibers, glass fibers, and thermoplastics—with stainless steel inserts, delivering exceptional lightness. Reference X82310281B1S1 has a 22mm lug width and water resistance designed for aquatic sports. The dial includes a date window; the tapered lug profile facilitates strap installation on the original spring bar system.

Frequently asked questions

What is the lug width of the Breitling Endurance Pro X82310281B1S1?

The lug width of the Breitling Endurance Pro X82310281B1S1 is 22mm. This is the internal measurement between the two lugs of the Titaplast case and corresponds to the strap width at the point of attachment to the case.

What is the best strap for the Breitling Endurance Pro?

It depends on the intended use. For sport activities, a technical nylon NATO or a vulcanised rubber strap offers durability and breathability. For a mixed sport-formal context, a vegetable-tanned calfskin strap in smooth finish provides excellent versatility. For formal occasions, a matte alligator belly strap with a deployant clasp enhances the case without compromising its technical identity.

How do you change the strap on the Breitling Endurance Pro?

The strap is replaced by operating on the spring bars located within the lugs of the case. Using a flat-tipped spring bar tool or an angled screwdriver, compress the spring bar to release it from the lug. Care must be taken to avoid scratching the Titaplast case. Fitting a new strap is carried out in reverse, inserting one end of the spring bar first, then compressing the other end to engage it.

Are there aftermarket straps compatible with the 22mm Endurance Pro?

Yes, any strap with a 22mm lug width is technically compatible with the Breitling Endurance Pro. Milano Straps offers a selection of handcrafted straps in alligator, calfskin, NATO and rubber, specifically sized to 22mm, available online with fast delivery or customisable at the Casati Milano atelier.

How long does a leather strap last on a sports watch like the Endurance Pro?

The lifespan of a leather strap depends primarily on exposure to perspiration, water and heat. On a sports watch with intensive use, a standard calfskin strap may last 12 to 18 months. Higher-quality vegetable-tanned leather straps, when treated with conditioning creams and protected from water, can last 2 to 3 years or more. For continuous sporting use, it is advisable to alternate with a rubber or NATO strap.
