Frequently asked questions

What is the lug width of the Breitling Avenger A13381111C1S1?

The lug width of the Breitling Avenger A13381111C1S1 is 22mm. This measurement is consistent across all production examples of this reference and defines the strap size required. To confirm this on your own watch, measure the internal distance between the two lower lugs using a digital calliper.

What is the best strap for the Breitling Avenger A13381111C1S1?

The ideal choice depends on intended use. For formal or semi-formal contexts, an alligator leather strap in matte finish or a shell cordovan in tobacco brown or black complements the 43mm steel case effectively. For sport use or humid environments, a ballistic nylon NATO or a vulcanised rubber strap is more appropriate. In all cases, the required lug width is 22mm.

How do you change the strap on a Breitling Avenger A13381111C1S1?

To replace the strap on the Avenger A13381111C1S1, a double-tipped spring bar tool is required. The spring bars are located within the lugs: inserting the tool tip into the spring bar slot compresses the spring and releases the strap. The operation takes under two minutes and requires no professional equipment, though care should be taken to avoid scratching the steel lugs.

Are there aftermarket straps compatible with the Breitling Avenger A13381111C1S1?

Yes. Any strap with a straight 22mm end is compatible with the Breitling Avenger A13381111C1S1. Milano Straps offers a curated selection of handcrafted 22mm straps in vegetable-tanned leather, alligator, shell cordovan, NATO nylon, and rubber — available bespoke or from stock. Breitling-branded straps are not required to achieve an aesthetically and functionally superior result.

How long does a leather strap last on a Breitling Avenger A13381111C1S1?

Longevity depends on leather quality and frequency of use. A high-grade vegetable-tanned leather strap, properly conditioned, can last between three and seven years with regular wear. Shell cordovan, owing to its densely packed fibre structure, outlasts standard calf leather significantly. Prolonged exposure to water, perspiration, and UV radiation accelerates deterioration; for intensive use, rotating between two straps or opting for technical materials is advisable.
