What I'm asked about the Rado Oval R15518152
What strap size does the Rado Oval R15518152 take?
The Rado Oval R15518152 needs 20 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Rado Oval R15518152 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 Rado Oval R15518152?
Yes, in 20 mm leather. On a 38 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Rado Oval R15518152?
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.
