What I'm asked about the Rolex Datejust 31 178383-0019

What strap size does the Rolex Datejust 31 178383-0019 take?

The Rolex Datejust 31 178383-0019 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 178383-0019 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 178383-0019?

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 178383-0019?

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.
