Strap for Super Avenger Silver / Stick

The lug width of the Breitling Avenger A1337011.A660 is 20mm. This measurement refers to the internal distance between the two lugs of the case and is the key parameter for identifying compatible straps. It is advisable to verify this with a digital calliper before purchasing an aftermarket strap.

For the Breitling Avenger A1337011.A660, with its 48.40mm case and instrument-watch character, the most suitable straps are: square-scale alligator in vegetable tanning for formal contexts, box calf leather for elegant daily wear, vulcanised rubber for sports use, and ballistic nylon NATO for maximum fidelity to the tool-watch identity. The choice depends on intended use and desired colour pairing.

To replace the strap on the Breitling Avenger A1337011.A660, a double-tip spring bar tool (ideally with a fork tip) of 1.5mm is required. Insert the tool into the notch on the lug, compress the spring bar inward and slide the strap free. Repeat on the other side. Fitting is carried out in reverse order. It is recommended to work on a soft surface to avoid scratching the case.

Yes, the Breitling Avenger A1337011.A660 uses a standard 20mm lug attachment that ensures full compatibility with aftermarket straps from any manufacturer. Milano Straps offers a curated selection of handcrafted leather, rubber and nylon straps available specifically in 20mm, with a bespoke option crafted by Casati Milano atelier for those seeking a fully personalised strap.

The lifespan of a leather strap depends on the quality of the hide, the tanning process and daily usage. A high-quality vegetable-tanned alligator strap can last between 3 and 6 years with proper care (avoiding water exposure, applying conditioning cream every 3–4 months). Box calf leather offers a similar durability. Frequent exposure to perspiration or water significantly shortens the strap's life: in such cases, rubber or NATO straps are preferable.
