What I'm asked about the Breitling Chronomat Evolution A1335611/B721

What strap size does the Breitling Chronomat Evolution A1335611/B721 take?

The Breitling Chronomat Evolution A1335611/B721 needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Breitling Chronomat Evolution A1335611/B721 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 Chronomat Evolution A1335611/B721?

Yes, in 20 mm leather. On a 44 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Breitling Chronomat Evolution A1335611/B721?

A 20 mm box calf. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
