The ready-to-wear strap is 115 × 75 mm. For a smaller or larger wrist I make it in the right length: order your length.
What I'm asked about the Rolex Datejust 16234
What strap size does the Rolex Datejust 16234 take?
The Rolex Datejust 16234 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 Rolex Datejust 16234 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 16234?
Yes, in 20 mm leather. On a 36 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Rolex Datejust 16234?
A 20 mm calf strap, for every day. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
