What I'm asked about the Breitling Chronomat A10320101A1A1
What strap size does the Breitling Chronomat A10320101A1A1 take?
The Breitling Chronomat A10320101A1A1 needs 16 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Breitling Chronomat A10320101A1A1 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 A10320101A1A1?
Yes, in 16 mm leather. On a 36 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Breitling Chronomat A10320101A1A1?
A 16 mm box calf. You'll find it ready in the 16 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
