What I'm asked about the Breitling AVI A45330101C1X4
What strap size does the Breitling AVI A45330101C1X4 take?
The Breitling AVI A45330101C1X4 needs 21 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Breitling AVI A45330101C1X4 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 A45330101C1X4?
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 A45330101C1X4?
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.
