Strap for Super Avenger

The lug width of the Breitling Avenger A1337011.B907.135S is 20 mm. This measurement is taken with a digital calliper positioned internally between the lugs, flush against the case middle. Despite the oversize 48.40 mm case diameter, Breitling opted for a standard 20 mm lug width, ensuring broad compatibility with high-quality aftermarket straps.

For the Breitling Avenger A1337011.B907.135S, the most suitable materials are hornback or belly alligator, which visually anchors the 48.40 mm case, vegetable-tanned calfskin for a developing patina over time, and shell cordovan for its dense grain and resistance to deformation under the keeper. For sport or operational use, vulcanised rubber or ballistic nylon NATO straps are functionally consistent with the tool-watch character of this piece.

To replace the strap on the Breitling Avenger A1337011.B907.135S, use a fine-tipped or forked spring bar tool. Insert the tip into the lug slot on the inner side of the lug, compress the spring bar, and slide it out. Take care not to scratch the satin-finished steel lugs. Work on a soft surface and, if in doubt, entrust the operation to a watchmaker or the Casati Milano atelier.

Yes, any strap with a 20 mm attachment width is technically compatible with the Breitling Avenger A1337011.B907.135S. Milanostraps.it offers a curated selection of 20 mm straps in various materials and lengths. For optimal proportions, a standard 120/75 mm or long 130/80 mm length is recommended depending on wrist circumference, with a square-cut end for a clean fit against the lug.

The lifespan of a leather strap depends on tanning quality, daily use and care. A high-quality strap in alligator or shell cordovan, with regular wear, typically lasts between two and five years. Factors such as perspiration, water exposure and buckle pressure at the holes accelerate wear. Casati Milano straps carry an 18-month guarantee against manufacturing defects and are crafted from selected hides to maximise longevity.
