Strap for Super Avenger II Stainless Steel / Volcano Black / Bracelet

The lug width of the Breitling Avenger A13371111B1A1 is 24mm. This measurement refers to the internal diameter of the metal tubes connecting the lugs to the case. To verify, measure with a digital calliper the distance between the two tubular sections on the inner face of the lug, excluding any leather or strap already installed.

Material choice depends on intended use. For purist aesthetics and natural ageing, black alligator is ideal: it offers pronounced grain and develops golden patina over time. For everyday wear and flexibility, vegetable-tanned calf balances lightness with texture that progressively softens. For sporting contexts or humid environments, NATO straps in 1000D ballistic canvas offer durability and rapid drying. Shell cordovan represents a middle ground with excellent value proposition.

The Breitling Avenger A13371111B1A1 features pin-through lugs. Obtain a spring bar tool or small nylon lever. Insert the flat end of the tool into the access hole beneath the lug, gently press toward the centre of the case to release the internal spring, then slide the metal tube out of its seats. Repeat on the opposite lug. To install the new strap, insert the metal tubes of the replacement strap into the vacant positions and allow the spring to reposition automatically.

Yes, completely. Any strap with 24mm lug width is mechanically compatible. Check thickness carefully: thin straps (below 3.5-4mm) may show excessive play in the metal tubes; conversely, thicknesses exceeding 5mm may fit slightly tight. Artisan straps from Milano Straps, constructed with precision bespoke sizing, fit perfectly and maintain structural integrity over time, ensuring fit consistency with your Avenger's horological quality.

A high-quality alligator or calf strap, subject to moderate daily use (4-5 days per week), maintains structural integrity for 3-4 years before visible wear appears. Shell cordovan, being more compact, can achieve 4-5 years. Factors including humidity, perspiration, direct sunlight exposure, and repeated contact with rough surfaces accelerate degradation. Vegetable tanning, particularly, develops natural protective patina that delays ageing. Straps with 18-month warranty like those from Casati Milano include free replacement should the leather fail prematurely, independent of construction defects.
