Frequently asked questions

What is the lug width of the Breitling Endurance Pro X823102A1B1S1?

The lug width of the Breitling Endurance Pro X823102A1B1S1 is 22mm. This measurement is taken internally between the two lugs of the case, where the strap attaches. Any 22mm strap is directly compatible with this reference.

What is the best strap for the Breitling Endurance Pro X823102A1B1S1?

The ideal choice depends on the context. For sport and water use, a vulcanised rubber or nylon NATO strap in 22mm is the most practical option. For daily or semi-formal wear, a high-quality calfskin or vegetable-tanned leather strap offers durability and refined aesthetics. For formal occasions, a matte alligator strap with contrast stitching complements the technical dial beautifully.

How do you change the strap on the Breitling Endurance Pro X823102A1B1S1?

The strap is removed using a spring bar tool — a flat-tipped lever or dedicated pin tool. Compress the spring bar on one side to release it from the lug, then repeat on the other side. The operation takes just a few minutes and does not require professional watchmaking assistance. If in doubt, our Casati Milano atelier can perform the swap by appointment.

Are there aftermarket straps compatible with the Breitling Endurance Pro X823102A1B1S1?

Yes. Any strap with a 22mm attachment width is technically compatible with the Breitling Endurance Pro X823102A1B1S1. Milano Straps offers a curated selection of handcrafted leather, rubber, and nylon straps, made from premium materials and available in various lengths and finishes to suit any wrist size and style preference.

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

The lifespan of a leather strap depends on frequency of use and exposure to sweat and moisture. On a sports watch, a quality vegetable-tanned leather strap typically lasts 2 to 4 years with standard care. Use in water or during intense physical activity accelerates wear: in such conditions, alternating with a rubber or NATO strap is advisable. All Milano Straps products carry an 18-month warranty against manufacturing defects.
