What I'm asked about the Oris Classic 01 733 7578 4031-07 5 18 10

What strap size does the Oris Classic 01 733 7578 4031-07 5 18 10 take?

The Oris Classic 01 733 7578 4031-07 5 18 10 needs 18 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Oris Classic 01 733 7578 4031-07 5 18 10 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 Classic 01 733 7578 4031-07 5 18 10?

Yes, in 18 mm leather. On a 37 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.

Which strap do you recommend for the Oris Classic 01 733 7578 4031-07 5 18 10?

A thin 18 mm alligator. You'll find it ready in the 18 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
