Strap for Avenger II Stainless Steel / Mariner Blue / Calf / Folding

The lug width of the Breitling Avenger A1338111/C870/436X/A20D.1 is 22mm. This measurement refers to the internal distance between the case lugs — the protruding extensions at the top and bottom of the case — where the strap is fitted. To verify this on your own piece, use a digital calliper to measure the clear gap between the two lugs at the point of contact with the strap.

The most suitable straps for the Breitling Avenger A1338111/C870/436X/A20D.1 are: vegetable-tanned Tuscan calfskin leather for everyday use with natural patina development over time; hornback alligator for formal occasions; ballistic nylon NATO for sporting and operational use; and vulcanised rubber for aquatic environments or high-humidity conditions. The correct width is 22mm, with a buckle or deployant clasp of 20mm to ensure a proportionate attachment.

To replace the strap on the Breitling Avenger A1338111/C870/436X/A20D.1, the spring bars securing the strap to the case lugs must be removed. A spring bar tool — a forked-lever instrument — is used to compress the ends of the spring bar inward, releasing it from its housing. Care should be taken not to scratch the stainless steel case: it is advisable to protect the lugs with low-tack adhesive tape before proceeding.

Yes, a wide range of aftermarket straps is compatible with the Breitling Avenger A1338111/C870/436X/A20D.1. The key parameter is the 22mm lug width: any strap with this measurement will fit the case lugs correctly. Milano Straps offers a curated selection of handcrafted 22mm straps in various materials — Tuscan leather, alligator, shell cordovan, NATO nylon and rubber — available bespoke or ready to ship.

The lifespan of a leather strap on a Breitling Avenger depends primarily on the quality of the hide, the tanning method used, and the intensity of daily wear. A good quality vegetable-tanned calfskin strap worn daily will typically last between 2 and 4 years. Alligator or shell cordovan straps, owing to the density of their fibres, can exceed 5 years with standard care. Prolonged exposure to water, excessive perspiration and direct sunlight should be avoided, and a conditioning balm should be applied periodically to maintain the leather's suppleness.
