What I'm asked about the Rolex Datejust 31 178159-0061

What strap size does the Rolex Datejust 31 178159-0061 take?

The Rolex Datejust 31 178159-0061 needs 16 mm between the lugs, usually 14 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Rolex Datejust 31 178159-0061 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 Datejust 31 178159-0061?

Yes, in 16 mm leather. On a 31 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Rolex Datejust 31 178159-0061?

A 16 mm calf strap, for every day. You'll find it ready in the 16 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
