Strap for Avenger II Stainless Steel / Tungsten Gray / Calf / Folding

The lug width of the Breitling Avenger A1338111/F564/436X/A20D.1 is 22mm. This measurement is declared by Breitling for the entire 43mm Avenger line and corresponds to the internal distance between the lugs at the strap attachment point. It can be verified with a millimetre calliper directly on the watch.

Four options are recommended for this model: vegetable-tanned calf leather with a pronounced grain (excellent ageing and patina development), hand-finished alligator for more formal occasions, black vulcanised rubber for maximum water resistance, and ballistic nylon NATO for consistency with the model's operational origins. The correct width is 22mm.

The strap is removed using a spring bar tool, a forked-tip instrument available from watchmakers. Apply gentle lateral pressure on the spring bar pins to release them from the lugs. The operation does not require case back removal and requires no specialist skills, though it is advisable to work on a soft surface to avoid scratching the case.

Yes. Any 22mm strap with a standard spring bar attachment is compatible with this reference. Milano Straps offers a selection of handcrafted leather, rubber and nylon straps made specifically for watches with a 22mm lug width, including Breitling Avenger models. The buckle or folding deployant clasp can be matched in steel to maintain visual consistency with the original case.

The lifespan of a leather strap depends on leather quality, care and intensity of use. A high-quality vegetable-tanned calf leather strap, kept away from prolonged sweat and water exposure and treated periodically with leather conditioner, can last between 2 and 5 years while retaining its structural and aesthetic integrity. Shell cordovan and alligator straps generally offer greater longevity due to the higher fibre density of the leather.
