Strap for Super Avenger II Stainless Steel / Mariner Blue / Calf / Pin

The lug width of the Breitling Avenger A1337111/C871/101X/A20BA.1 is 24mm. This measurement is specific to larger timepieces exceeding 42mm in case diameter, ensuring balanced proportions on the wrist. To verify strap compatibility, measure the internal distance between the case lugs: it must be exactly 24mm.

For the Breitling Avenger A1337111/C871/101X/A20BA.1, we recommend premium alligator leather for formal luxury aesthetics, or vegetable-tanned calf for artisanal authenticity and natural ageing characteristics. A NATO strap remains the historically accurate choice for emphasising the watch's tactical heritage. For sports applications, technical rubber offers maximum functionality and durability.

Gently slide the spring bars out from the case lugs by orienting the strap inward toward the wrist. No specialised tools are required if the lugs are solid. Align the new strap attachments with the case lugs and firmly push outward until you feel the securing click. Always verify the lug bars are properly seated before wearing.

Yes, any strap featuring 24mm lug width is compatible with the A1337111/C871/101X/A20BA.1. Milanostraps provides a specialised collection of 24mm straps in alligator, calf, NATO, and technical rubber—all customisable in length, colour, and thread colour for a precise fit on your wrist.

A premium leather strap, whether vegetable-tanned or alligator, typically lasts 3–5 years under regular use, depending on sun exposure, humidity, and wear frequency. Vegetable-tanned leather develops a rich patina over time. Casati Milano guarantees 18 months on every bespoke strap and recommends seasonal maintenance with specialist leather conditioners to extend lifespan.
