Frequently asked questions

What is the lug width of the Breitling Endurance Pro E823106A1BAS1?

The lug width of the Breitling Endurance Pro E823106A1BAS1 is 22mm. This measurement is consistent across the entire Endurance Pro range and can be confirmed with a digital calliper measuring the internal distance between the two lugs on the case.

What is the best strap for the Breitling Endurance Pro E823106A1BAS1?

The optimal choice depends on intended use. For intense sporting activity, a vulcanised rubber or silicone strap offers full water resistance and secure grip. For mixed sport-professional wear, vegetable-tanned calfskin strikes the ideal balance. For formal occasions, a matte alligator strap with contrast stitching lends the titanium case an unexpectedly refined, sartorial quality.

How do you change the strap on a Breitling Endurance Pro E823106A1BAS1?

The Breitling Endurance Pro features a quick-release mechanism on the spring bar, allowing strap changes without tools by pressing the side release button on the bar. For aftermarket straps fitted with standard spring bars, a flat-head strap-changing tool is sufficient to complete the swap independently in a matter of seconds.

Are there aftermarket straps compatible with the Breitling Endurance Pro E823106A1BAS1?

Yes. Any strap with a 22mm lug width is technically compatible. Milano Straps offers a curated selection of handcrafted straps in various materials — calfskin, alligator, nylon NATO and rubber — specifically designed for this lug size. Italian artisan quality ensures finishes and materials that surpass the standard Breitling OEM offering.

How long does a leather strap last on the Breitling Endurance Pro E823106A1BAS1?

The lifespan of a leather strap depends on the quality of the tanning, frequency of use, and exposure to perspiration and moisture. A vegetable-tanned calfskin strap used in non-intensive sporting contexts has an average lifespan of 18–36 months. Alligator or shell cordovan straps, with proper conditioning, can exceed 4–5 years while developing a rich, characterful patina.
