Strap for Super Avenger II Stainless Steel / Diamond / Stratus Silver / Calf / Pin

The Breitling Avenger A1337153/G779/439X/A20BA.1 features a 24-millimetre lug width. This dimension, slightly above the conventional 20mm standard, is specific to this model and requires compatibly drilled straps. Construction tolerance is ±0.5mm: always measure with a digital calliper between the internal shoulders of the lugs to verify compatibility of any aftermarket strap.

For the Avenger A1337153/G779/439X/A20BA.1 in stainless steel, three profiles are ideal. Mississippi alligator delivers lasting elegance with sophisticated natural patina; vegetable-tanned calf guarantees visible and noble ageing; technical rubber or NATO ensures maximum functionality in operational environments. The choice depends on use context: alligator for formal and collected wear, calf for conscientious daily maintenance, rubber for absolute absence of compromise.

Changing the strap on an Avenger A1337153/G779/439X/A20BA.1 requires a spring bar removal tool. Support the case on a soft surface, insert the tool into the groove of the lower lug pin to compress the internal spring, then extract the pin downward. Repeat for the second pin. Insert the new pins into the 24mm strap with drilled holes aligned, then compress the upper pin until it clicks into position. Verify final tightness by applying light upward pressure.

Yes, provided the strap possesses an internal drilled width of 24mm, measured between the internal shoulders. Quality artisanal aftermarket straps respect these construction specifications. It is advisable to purchase from suppliers that certify lug width; your Avenger presents no anomalous geometry, so any professional 24mm strap assembles without forcing or improvised modifications.

A quality artisanal alligator or calf strap, worn on a 48mm chronograph used daily, has an average lifespan of 4–6 years before replacement is needed. Leather undergoes natural ageing, not deterioration: the grain deepens, the tone darkens, flexibility modulates. In intensely humid environments (frequent water exposure), lifespan reduces to 2–3 years. NATO or technical rubber straps maintain structural properties unchanged for 5–8 years, depending on UV exposure and cleaning frequency.
