The Avenger A13371111C1S1, seen from the bench

The Breitling Avenger A13371111C1S1 is a tactical chronograph designed for military pilots, professional divers, and search-and-rescue operators. This 48 mm stainless steel case houses the Breitling 13 calibre automatic movement with column-wheel chronograph, date function, and small seconds counter at six o'clock. The lug width is 24 mm. High-visibility SuperLuminova-filled hands and applied indices on a black dial ensure readability in extreme conditions. The unidirectional bezel and transparent caseback showcase the Geneva-striped nickel movement.

Frequently asked questions

What is the lug width of the Breitling Avenger A13371111C1S1?

The lug width of the Breitling Avenger A13371111C1S1 is 24 millimetres. This dimension replicates the vintage aviation standard, ensuring harmonious proportions on standard male wrists and preventing the lug droop effect typical of undersized straps on large-diameter watches. Measurement should be taken between the inner edges of the opposite lugs, from the lower attachment point of the spring bar. Straps of different diameters (22 or 26 millimetres) will not fit without risking structural damage.

Which strap is most suitable for the Breitling Avenger A13371111C1S1?

For this reference, we recommend three primary choices depending on context: 1) Vegetable-tanned leather in matte black, which creates sober monochromatics ideal in tactical and military contexts; 2) Alligator in cognac tone, which generates elegant contrast with the steel case and develops patina over time; 3) NATO strap in charcoal grey or military sage green, which amplifies the original operative heritage. For professionals operating in aquatic or chemical environments, fluoroelastomer ensures superior resistance to chlorine and sea salt.

How do you change the strap on a Breitling Avenger?

The strap is replaced via the spring bars positioned at the two 24-millimetre lugs. Using a dedicated tool (spring bar tool) or a blunted toothpick, gently push the spring inward towards the case, sliding the old strap until it releases. Once removed, align the new strap to the lugs and push the spring into its seat, verifying an audible click or tactile sense of arrest. Work cautiously to avoid scratching the case; never force the springs, as permanent damage may occur.

Is an aftermarket strap compatible with the Breitling Avenger A13371111C1S1?

Yes, provided it is manufactured for the 24-millimetre lug width. Quality aftermarket straps—in vegetable leather, alligator, shell cordovan or synthetic materials—offer aesthetic and functional versatility over original straps. Always verify that the attachment springs are the correct size (24 millimetres) and that materials are of proven durability. Specialist suppliers such as Milano Straps guarantee certified compatibility and bespoke customisations in size, length and stitching thread.

How long does a leather strap last on a Breitling Avenger?

Lifespan depends on material and wear frequency. A high-quality leather strap (European vegetable-tanned, alligator, shell cordovan) typically lasts 5–7 years with daily wear, developing patina and character over time. Longevity increases significantly if the strap is rotated amongst at least three alternatives, allowing the leather to breathe and dry completely. Factors such as ambient humidity, perspiration and sun exposure accelerate ageing: appropriate periodic maintenance (gentle cleaning, conditioning with natural oils) can extend life to 10 years. Fluoroelastomer straps last 8–12 years with minimal aesthetic variation.
