What I'm asked about the Oris BC4 01 653 7631 4684-Set

What strap size does the Oris BC4 01 653 7631 4684-Set take?

The Oris BC4 01 653 7631 4684-Set 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 01 653 7631 4684-Set 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 01 653 7631 4684-Set?

Yes, in 24 mm leather. On a 45 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Oris BC4 01 653 7631 4684-Set?

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