What I'm asked about the Rolex Oyster Perpetual 34 124200-0003
What strap size does the Rolex Oyster Perpetual 34 124200-0003 take?
The Rolex Oyster Perpetual 34 124200-0003 needs 18 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 Oyster Perpetual 34 124200-0003 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 Oyster Perpetual 34 124200-0003?
Yes, in 18 mm leather. On a 34 mm case a calf strap works every day; if you want something more, alligator.

A 18 mm calf strap, for every day. You'll find it ready in the 18 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
