Strap for Super Avenger II Stainless Steel / Diamond / Mariner Blue / Bracelet

The lug width of the Breitling Avenger A1337153/C871/168A is 24mm. This is the internal distance between the two spring bar pins. To measure correctly, use a digital calliper positioned perpendicularly between the two lug holes, not across the visual width of the case (which is 48mm). This width is standard for Breitling chronographs in this category.

For the Breitling Avenger A1337153/C871/168A we recommend three solutions: alligator with vegetable tanning (dark brown or havana) for robust elegance; shell cordovan in dark tones (burgundy or deep brown) for longevity and natural patina; vulcanised rubber in black with satin grain for active tactical use. Your choice depends on context: formal/everyday, professional sport, or marine and high-stress environments.

The strap is changed by removing the spring bar from the two lug pins that support it. You'll need a spring bar tool, which allows you to compress the spring to extract it from the holes. Position the old strap horizontally, insert the flat tip of the spring bar tool into one of the lateral grooves of the spring, compress gently, and extract the pin. Repeat on the other side. Insert the new strap by aligning the lug holes with the pins, then press the spring until you hear a slight click. The procedure takes 3-5 minutes and requires no specialist skills.

Yes, any strap with a 24mm lug width is mechanically compatible with the Breitling Avenger A1337153/C871/168A. Aftermarket straps in leather, rubber, fabric or metal at 24mm width mount without need for adapters or reducers. Mechanical compatibility is assured; your choice should be guided by material (alligator, calf, shell cordovan, rubber, NATO), finish and colour according to use context and personal aesthetic preference.

Durability depends on material and tanning type. An ordinary calf strap with chrome tanning lasts 3-5 years in moderate use (worn 5-7 days weekly). An alligator strap with vegetable tanning resists 5-8 years thanks to more robust fibre structure and develops authenticating patina over time. Shell cordovan, particularly dense and fibrous, can exceed 10 years of active use. Vulcanised rubber has service cycles similar to calf but resists moisture and chemical agents better. Regular maintenance (cleaning, seasonal conditioning) significantly extends the lifespan of any natural material strap.
