What I'm asked about the Rolex Day-Date II 218238-0038

What strap size does the Rolex Day-Date II 218238-0038 take?

The Rolex Day-Date II 218238-0038 needs 21 mm between the lugs, usually 18 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Rolex Day-Date II 218238-0038 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 Rolex Day-Date II 218238-0038?

Yes, in 21 mm leather. On a 41 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Rolex Day-Date II 218238-0038?

A 21 mm calf strap, for every day. You'll find it ready in the 21 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
