Strap for Avenger II Seawolf Stainless Steel / Volcano Black / Rubber / Pin

The lug width of the Breitling Avenger A1733110/BC30/158S/A20SS.1 is 22mm. This measurement can be verified directly on the case using a digital calliper, measuring the internal gap between the two lugs at the lower end of the case. Any 22mm strap is fully compatible with this reference.

For the 45mm Breitling Avenger A1733110/BC30/158S/A20SS.1, the most suitable options include vegetable-tanned alligator for a formal-sport context, barenia calf or vulcanised rubber for outdoor use, and a premium nylon NATO strap to honour the watch's aeronautical heritage. A steel deployant clasp completes the pairing in a manner coherent with the instrument aesthetic of this Avenger.

To replace the strap on the Avenger A1733110/BC30/158S/A20SS.1, you will need a fine-tipped spring bar tool. The lugs on this model accommodate standard 22mm spring bars. Compress the spring bar inward against the lug slot, slide out the old strap and insert the new one. No specialist tools are required, though working on a soft surface is advisable to avoid scratching the case.

Yes, any strap with a 22mm attachment width is compatible with the Breitling Avenger A1733110/BC30/158S/A20SS.1. Milano Straps offers a curated range of handcrafted straps in leather, alligator, shell cordovan and technical materials, all specifically produced for this lug width, with standard and XL length options for larger wrists. The artisanal quality is comparable or superior to the original Breitling accessory.

The lifespan of a leather strap depends on the material, frequency of use and level of care. On a 45mm Avenger — a heavy watch with a wide case — a quality artisanal alligator or vegetable-tanned calf strap can last between three and seven years with regular wear. Exposure to perspiration, water and UV light accelerates deterioration. Shell cordovan and well-maintained alligator straps develop a patina over time without compromising structural integrity.
