The Avenger A1337111/C871/154S/A20S.1, seen from the bench

The Breitling Avenger A1337111/C871/154S/A20S.1 is a 48mm stainless steel chronograph built for extreme environments including deep oceanic and military operations. It features a black dial with luminous indices, the in-house Breitling Caliber 13 automatic movement with chronograph function, and water resistance to 300 meters. The 24mm lug width accommodates this watch in an intermediate category between conventional sports chronographs and expedition-grade instruments.

Frequently asked questions

What is the lug width of the Breitling Avenger A1337111/C871/154S/A20S.1?

The lug width is precisely 24 millimetres, measured from the distance between the two spring bars that attach the strap to the case. To confirm compatibility, position a digital calliper directly above one spring bar and measure to the opposite bar. Straps of 23.5 or 24.5 mm will cause excessive play or mounting difficulties.

Which strap is best suited for the Breitling Avenger A1337111/C871/154S/A20S.1?

The choice depends on primary use. For maritime or diving environments, vulcanised rubber or premium NATO offer superior water resistance. For formal contexts, alligator or shell cordovan provide elegance with durability. For daily versatility, an interwoven NATO fabric in cotton or nylon represents the optimal compromise between easy maintenance and balanced aesthetics.

How do you change the strap on a watch with 24mm lugs?

Position the watch on a soft cushion. Using a spring bar tool or fine needle, gently push the spring bar from the opposite side until extraction. Repeat for the second bar. Insert the bars into the new strap by aligning the holes, then press them into position with the spring bar tool. Check that the strap is centred and the bars are fully seated.

Is a 24mm aftermarket strap compatible with the Breitling Avenger A1337111/C871/154S/A20S.1?

Yes, provided the lug width is certified at exactly 24mm. High-quality aftermarket straps (leather, NATO, rubber) are universally compatible as long as they respect this dimension. Always verify the specific lug width with the seller to avoid mounting issues.

How long does a leather strap last on a watch like the Avenger?

Durability varies by material and maintenance. Quality alligator lasts 5–8 years with ordinary care (avoid prolonged immersion). Shell cordovan, if treated with natural oils every 12–18 months, reaches 8–12 years. Vegetable-tanned calf typically lasts 3–5 years. Rubber and NATO have indefinite durability if not exposed to continuous UV rays; rubber degrades within 4–6 years of constant direct sunlight exposure.
