What I'm asked about the Breitling Chronomat RB01366A1L2S1
What strap size does the Breitling Chronomat RB01366A1L2S1 take?
The Breitling Chronomat RB01366A1L2S1 needs 22 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Breitling Chronomat RB01366A1L2S1 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 RB01366A1L2S1?
Yes, in 22 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 RB01366A1L2S1?
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.
