Frequently asked questions

What is the lug width of the Breitling Endurance Pro X82310A71B1S2?

The lug width of the Breitling Endurance Pro X82310A71B1S2 is 22mm. This measurement is taken with a vernier calliper across the internal distance between the two lugs, close to the case. It is a standardised width that ensures broad compatibility with aftermarket straps.

What is the best strap for the Breitling Endurance Pro X82310A71B1S2?

The ideal choice depends on intended use. For pure sporting use, a vulcanised rubber or heavy-duty NATO nylon strap in 22mm is the most practical option. For hybrid sport-formal wear, a vegetable-tanned calf leather strap in neutral tones offers versatility. For evening occasions, a matt alligator strap in black or midnight blue elevates the dial's character whilst respecting the Titaplast case's athletic aesthetic.

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

The strap is removed using a spring bar tool to compress the spring bars housed within the lug holes. This can be performed independently with the correct tools, or entrusted to a watchmaker or the Casati Milano atelier. It is advisable to work on a soft surface to avoid scratching the Titaplast case and bezel.

Are there aftermarket straps compatible with the Breitling Endurance Pro X82310A71B1S2?

Yes. Any strap with a 22mm lug width is technically compatible with the Breitling Endurance Pro X82310A71B1S2. Milano Straps offers an extensive selection of handcrafted straps in leather, rubber and textile in this width, made in Italy from selected materials and available with a buckle or deployant clasp.

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

The lifespan of a leather strap depends on the hide type and intensity of use. On a sports watch like the Endurance Pro, subject to perspiration and physical stress, a quality vegetable-tanned calf strap typically lasts 18 to 36 months with ordinary care. A high-grade alligator strap, owing to the density of its fibres, can exceed 3 to 5 years. Water immersion should be avoided, and alternating straps is recommended to extend their service life.
