What I'm asked about the Oris BC4 01 674 7633 4794-07 5 24 58BFC

What strap size does the Oris BC4 01 674 7633 4794-07 5 24 58BFC take?

The Oris BC4 01 674 7633 4794-07 5 24 58BFC 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 Oris BC4 01 674 7633 4794-07 5 24 58BFC 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 Oris BC4 01 674 7633 4794-07 5 24 58BFC?

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 Oris BC4 01 674 7633 4794-07 5 24 58BFC?

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.
