What I'm asked about the Breitling AVI A1731410

What strap size does the Breitling AVI A1731410 take?

The Breitling AVI A1731410 needs 21 mm between the lugs, usually 18 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Breitling AVI A1731410 be changed?

Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

Can I put a leather strap on the Breitling AVI A1731410?

Yes, in 21 mm leather. On a 41 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Breitling AVI A1731410?

A 21 mm box calf. You'll find it ready in the 21 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
