Strap for Avenger Blacksteel Águila Real Mexicana

The Breitling Avenger M13380 FT has a lug width of 22mm. This measurement is a direct consequence of the 45.40mm case diameter and can be verified using a calliper to measure the internal distance between the two lugs at the strap attachment point.

The choice depends on intended use. For professional or formal contexts, a matte alligator strap in vegetable-tanned leather with contrast stitching complements the case aesthetic most coherently. For sport or marine use, vulcanised rubber or ballistic nylon NATO straps offer durability and water resistance. Vegetable-tanned calf leather develops an authentic patina over time, making it ideal for daily wear.

The strap is removed using a springbar tool, inserting the tip into the springbar slot between the lug and the strap and compressing to release tension. Care should be taken to avoid scratching the stainless steel case — a soft cloth placed beneath the tool is recommended. The new 22mm strap is fitted by reversing the process, ensuring the springbars are correctly seated in both lug holes.

Yes. Any straight-end strap with a 22mm attachment width is compatible with the Breitling Avenger M13380 FT. Milano Straps offers a curated selection of handcrafted straps in various materials, all with straight ends suited to the lug geometry of this model. For a fully bespoke solution, Casati Milano atelier crafts made-to-measure straps tailored to the wearer.

Longevity depends on material, use and maintenance. A quality calf leather strap, conditioned with leather cream every 3–4 months and kept away from prolonged exposure to water and perspiration, will maintain structural integrity for 2–4 years of daily wear. Alligator leather, owing to its dense fibre structure, can last well over 5 years. Regular exposure to moisture or sweat accelerates deterioration; in such conditions, alternating with a rubber or NATO strap is advisable.
