Frequently asked questions

What is the lug width of the Breitling Avenger A32397101A1X1?

The Breitling Avenger A32397101A1X1 features 24-millimetre lug width. This size is specific to the 43mm case and is the standard specification you must search for when selecting an aftermarket compatible strap. To verify lug width, measure the distance between the inner points of both spring bar lugs, excluding the case itself.

Which strap do you recommend for the Breitling Avenger A32397101A1X1?

For the Avenger A32397101A1X1 we recommend alligator in black or chocolate brown for everyday aesthetic comfort, vegetable-tanned calf for those who appreciate patina development over time, or ballistic NATO strap in stone grey for tactical use. Choice depends on context: alligator for elegant versatility, calf for growing personal character, rubber or NATO for practicality and resistance. All our 24mm straps are compatible with this model's lugs.

How do I change the strap on my Breitling Avenger A32397101A1X1?

The Avenger A32397101A1X1 features straight spring bars (not screw-down). To change the strap: remove the original strap by pushing inward both spring bar pins with a dedicated tool, then extract the strap from the lugs. Insert the new 24mm strap by aligning the two holes with the lugs and allow the pins to snap into place. Verify that the pins are fully inserted and the strap sits securely. No special tools required.

Can I use a non-original aftermarket strap on my Breitling Avenger A32397101A1X1?

Absolutely. The 24mm lug width is an industry standard that allows you to fit straps from any artisanal manufacturer whilst respecting the measurement. Our straps are handcrafted from premium leathers (alligator, Italian calf, shell cordovan) with stainless steel or deployante hardware, guaranteeing full compatibility and durability superior to the original strap. Casati Milano warranty is 18 months on all handmade straps.

How long does a leather strap last on my Breitling Avenger A32397101A1X1?

Longevity depends on material and usage patterns. A quality alligator strap (such as ours) resists 4–6 years with moderate daily wear, as alligator is less porous than calf and withstands moisture better. Vegetable-tanned calf lasts 3–5 years whilst developing coveted patina. FKM rubber has maximum longevity (8–10 years) as it is not biodegradable. Wear increases if exposed to prolonged humidity, sweat or synthetic materials. Our straps can be reconditioned after expiry.
