What I'm asked about the Breitling Chronomat B01 42 AB01342B1C4S1

What strap size does the Breitling Chronomat B01 42 AB01342B1C4S1 take?

The Breitling Chronomat B01 42 AB01342B1C4S1 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 B01 42 AB01342B1C4S1 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 AB01342B1C4S1?

Yes, in 22 mm leather, as long as you don't wear it in the water: leather doesn't like the sea or the pool. For days in the water, rubber. On a 42 mm diver I go for a full-thickness strap, not a thin one.

Which strap do you recommend for the Breitling Chronomat B01 42 AB01342B1C4S1?

Rubber if you wear it in the water; otherwise a 22 mm calf strap, full thickness. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
