Strap for Avenger II Stainless Steel / Blue Impulse

The lug width of the Breitling Avenger A133811A/A811/170A is 22mm. This measurement is taken with a digital calliper at the narrowest point between the two lugs, flush against the case. Any strap with a 22mm attachment width is directly compatible with this reference.

The most suitable straps for the Breitling Avenger A133811A/A811/170A are: nylon NATO for maximum coherence with the aviator identity, vegetable-tanned calf leather in smooth or embossed grain for elegant daily wear, hornback or belly alligator for more formal occasions, and vulcanised rubber for sporting or water-related use. The ideal choice depends on the intended context and personal aesthetic preference.

To replace the strap on the Breitling Avenger A133811A/A811/170A, you will need a springbar tool. Insert the tip between the lug and the strap, compress the spring bar inward and slide the strap free. Take care not to scratch the stainless steel case: masking tape applied to the lugs before starting the operation is strongly recommended.

The lifespan of a leather strap on the Breitling Avenger A133811A/A811/170A depends on the type of leather, frequency of use and level of care. A quality vegetable-tanned calf leather strap worn daily and treated with nourishing cream will typically last 2–4 years. Alligator and shell cordovan, owing to their denser fibre structure, can exceed 5 years while retaining their shape and patina. Avoiding prolonged contact with water and perspiration significantly extends service life.
