What I'm asked about the Rolex Bubbleback 9291

What strap size does the Rolex Bubbleback 9291 take?

The Rolex Bubbleback 9291 needs 16 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Rolex Bubbleback 9291 be changed?

Yes, and easily: the lugs are drilled, so the spring bar is pushed out from the outside with a thin pin, without opening anything. If you prefer, I do it in the workshop.

Can I put a leather strap on the Rolex Bubbleback 9291?

Yes, in 16 mm leather. On a 32 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Rolex Bubbleback 9291?

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.
