Frequently asked questions

What is the lug width of the Breitling Endurance Pro X82310A51B1S2?

The lug width of the Breitling Endurance Pro X82310A51B1S2 is 22mm. This measurement is taken between the two lugs using a digital calliper and determines the correct strap size. Any 22mm strap with a straight end is compatible with this reference.

What is the best strap for the Breitling Endurance Pro X82310A51B1S2?

The ideal choice depends on intended use. For sport and outdoor activities, a 22mm ballistic nylon NATO or a vulcanised rubber strap offers moisture resistance and comfort under physical exertion. For smarter occasions, a vegetable-tanned calfskin or bombé alligator strap creates a deliberate contrast with the technical Breitlight® case. A butterfly deployant clasp ensures consistent positioning on the wrist in either scenario.

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

The strap is removed using a fine-tipped spring bar tool inserted into the gap between the strap end and the lug. The original spring bars measure 1.8mm in diameter; it is advisable to replace them alongside the strap to ensure reliable retention. The operation requires no specialist equipment and can be carried out at home with care, or entrusted to a watchmaker or the Casati Milano atelier.

Are there aftermarket straps compatible with the Breitling Endurance Pro X82310A51B1S2?

Yes. The Breitling Endurance Pro X82310A51B1S2 features a standard 22mm straight-end lug, making it compatible with any aftermarket strap in that size. Milano Straps offers a curated selection of handcrafted leather, NATO and rubber straps specifically sized at 22mm, with standard lengths (75/115mm) suitable for most wrist circumferences.

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

The lifespan of a leather strap depends primarily on exposure to perspiration, water and UV radiation. On a sport-oriented timepiece, a quality vegetable-tanned calfskin strap can last between 18 months and 3 years with regular wear, provided it is not subjected to prolonged water exposure and is allowed to air-dry after intensive use. Shell cordovan and vegetable-tanned alligator tend to offer greater longevity due to the density of their fibres.
