What I'm asked about the Rolex Daytona 126503-0003

What strap size does the Rolex Daytona 126503-0003 take?

The Rolex Daytona 126503-0003 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 Daytona 126503-0003 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 Daytona 126503-0003?

Yes, in 20 mm leather. On a 40 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Rolex Daytona 126503-0003?

A 20 mm box calf. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
