What I'm asked about the Bell & Ross Instruments BRX1-CHTB-RS17

What strap size does the Bell & Ross Instruments BRX1-CHTB-RS17 take?

The Bell & Ross Instruments BRX1-CHTB-RS17 needs 24 mm between the lugs, usually 20 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Bell & Ross Instruments BRX1-CHTB-RS17 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 Bell & Ross Instruments BRX1-CHTB-RS17?

Yes, in 24 mm leather. On a 45 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Bell & Ross Instruments BRX1-CHTB-RS17?

A 24 mm box calf. You'll find it ready in the 24 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
