What I'm asked about the Rolex Sky-Dweller 326939

What strap size does the Rolex Sky-Dweller 326939 take?

The Rolex Sky-Dweller 326939 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 Sky-Dweller 326939 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 Sky-Dweller 326939?

Yes, in 21 mm leather. On a 42 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Rolex Sky-Dweller 326939?

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.
