Frequently asked questions

What is the lug width of the Breitling Avenger A17318101B1X1?

The Breitling Avenger A17318101B1X1 has a lug width of 22mm. This measurement should be confirmed using a calliper, measured at the inner gap between the two lugs where the strap inserts into the case. All compatible 22mm straps are available at milanostraps.it.

What is the best strap for the Breitling Avenger A17318101B1X1?

The most suitable materials for the Breitling Avenger A17318101B1X1 are vegetable-tanned calf leather with a military grain, smooth alligator in dark tones (black or anthracite), and ballistic nylon NATO straps. The choice depends on intended use: formal, sporting, or aquatic. Vulcanised rubber is recommended for dives up to 300 metres.

How do you change the strap on the Breitling Avenger A17318101B1X1?

To replace the strap on the Breitling Avenger A17318101B1X1, use a rounded-tip springbar tool. Insert the tool into the lateral lug slot, compress the springbar spring and slide the strap free. The operation takes approximately two minutes and does not require sending the watch to an authorised service centre.

Are there aftermarket straps compatible with the Breitling Avenger A17318101B1X1?

Yes. Any strap with a 22mm attachment is compatible with the Breitling Avenger A17318101B1X1. milanostraps.it offers a curated selection of Italian handcrafted straps — in leather, rubber and NATO — designed to fit the lugs of this reference precisely, with deployant or tang buckle in stainless steel.

How long does a leather strap last on a Breitling Avenger A17318101B1X1?

Longevity depends on the material and conditions of use. A vegetable-tanned calf strap, properly maintained (conditioning cream every 2–3 months, dried after water exposure), typically lasts 2–4 years. Alligator, due to its denser fibre structure, can exceed 5 years. Vulcanised rubber does not degrade with humidity and is ideal for marine or intense sporting use. Casati Milano provides an 18-month warranty against manufacturing defects.
