What I'm asked about the Breitling Chronomat B01 42 AB0134101A1A1

What strap size does the Breitling Chronomat B01 42 AB0134101A1A1 take?

The Breitling Chronomat B01 42 AB0134101A1A1 needs 22 mm between the lugs, usually 18 or 20 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Breitling Chronomat B01 42 AB0134101A1A1 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 B01 42 AB0134101A1A1?

Yes, in 22 mm leather. On a 42 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Breitling Chronomat B01 42 AB0134101A1A1?

A 22 mm box calf. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
