Frequently asked questions

What is the lug width of the Breitling Endurance Pro E823101A1I1S1?

The Breitling Endurance Pro E823101A1I1S1 features a lug width of 22mm. This measurement refers to the internal distance between the two lugs and determines the correct strap width. Before purchasing an aftermarket strap, it is advisable to verify the measurement with a digital calliper to ensure a precise fit.

What is the best strap for the Breitling Endurance Pro E823101A1I1S1?

The ideal choice depends on the intended use. For sport and aquatic activities, an FKM or vulcanised rubber strap offers full waterproofness, grip and durability. For a more versatile register, vegetable-tanned calfskin with a pronounced grain pairs naturally with the matte texture of the titanium case. Alligator belly or hornback leather is the choice for those seeking a refined aesthetic contrast between the contemporary case and a noble material.

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

The Breitling Endurance Pro uses a standard spring bar system. A flat-head spring bar tool or a thin flathead screwdriver is sufficient to release the spring bars from the lugs, remove the old strap and fit the new one. It is recommended to work on a soft surface to avoid scratching the titanium case. If in doubt, Casati Milano offers an in-atelier strap fitting service.

Are there aftermarket straps compatible with the Breitling Endurance Pro E823101A1I1S1?

Yes. Any strap with a standard 22mm lug width and spring bar attachment is compatible with the Breitling Endurance Pro E823101A1I1S1. Milanostraps.it offers a curated selection of handcrafted 22mm straps in leather, alligator, calfskin and rubber, available in various lengths and finishes to suit any wrist size.

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

The lifespan of a leather strap depends on the quality of the hide, the tanning method and conditions of use. A handcrafted vegetable-tanned calfskin strap, with regular non-intensive daily wear, can last between 2 and 4 years, developing a distinctive patina over time. Prolonged exposure to perspiration, water or UV rays will accelerate deterioration: for intensive sport use, alternating with a rubber strap is strongly recommended. Milano Straps offers an 18-month guarantee against manufacturing defects.
