The ready-to-wear strap is 115 × 75 mm. For a smaller or larger wrist I make it in the right length: order your length.
What I'm asked about the Breitling Chronomat 28 A72310531G1A1
What strap size does the Breitling Chronomat 28 A72310531G1A1 take?
The Breitling Chronomat 28 A72310531G1A1 needs 14 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Breitling Chronomat 28 A72310531G1A1 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 28 A72310531G1A1?
Yes, in 14 mm leather. On a 28 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Breitling Chronomat 28 A72310531G1A1?
A 14 mm box calf. I don't keep this size ready in the catalogue: I make it to measure. If you'd rather have something built on your wrist, the Casati atelier.
