What I'm asked about the Oris Classic 01 733 7578 4361
What strap size does the Oris Classic 01 733 7578 4361 take?
The Oris Classic 01 733 7578 4361 needs 18 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Oris Classic 01 733 7578 4361 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 4361?
Yes, in 18 mm leather. On a 37 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.

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.
