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

The lug width of the Breitling Avenger A1338111/C870/433X/A20BA.1 is 22mm. This measurement is determined by the 43mm case architecture and the squared lug profile characteristic of the Avenger line. To confirm the measurement on your own piece, use a millimetre calliper between the two lugs.

For this reference, a vegetable-tanned calfskin strap with a medium grain is the most versatile option, developing a natural patina over time. A matte alligator strap adds refinement without betraying the instrument character of the watch. For sport or water-exposed use, a vulcanised rubber strap or a premium ballistic nylon NATO strap are the most coherent choices given the Avenger's tool watch DNA.

The strap is removed using a fine-tipped spring bar tool inserted into the spring bar slot on each lug. Standard 22mm spring bars compress laterally to release from their seats. Care should be taken not to scratch the steel lugs during the operation; it is advisable to protect the case with a soft cloth whilst swapping the strap.

Yes. Any strap with a 22mm lug width is compatible with this reference. Milano Straps offers a curated selection of handcrafted Made in Italy straps in various leathers and finishes, available in the correct size. It is important to ensure that the supplied spring bars have the correct diameter for the Avenger's lugs, which are relatively deep to guarantee secure retention under intensive use.

Longevity depends on leather quality, frequency of use, and exposure to perspiration and water. A high-quality vegetable-tanned calfskin strap, rotated with other straps and kept away from water, can last between three and five years whilst retaining its structural and aesthetic integrity. Premium alligator straps, owing to the density of their fibre structure, often last considerably longer, developing a distinguished patina. Milano Straps guarantees its straps for 18 months against manufacturing defects.
