What I'm asked about the Omega De Ville 7813.50.31

What strap size does the Omega De Ville 7813.50.31 take?

The Omega De Ville 7813.50.31 needs 20 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 Omega De Ville 7813.50.31 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 Omega De Ville 7813.50.31?

Yes, in 20 mm leather. On a 35 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.

Which strap do you recommend for the Omega De Ville 7813.50.31?

A thin 20 mm alligator. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
