What I'm asked about the Breitling Chronomat 40 GMT A32398E31C1A1

What strap size does the Breitling Chronomat 40 GMT A32398E31C1A1 take?

The Breitling Chronomat 40 GMT A32398E31C1A1 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 40 GMT A32398E31C1A1 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 40 GMT A32398E31C1A1?

Yes, in 20 mm leather. On a 40 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Breitling Chronomat 40 GMT A32398E31C1A1?

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.
