Can the strap on the Rolex Oyster Perpetual 100th - 31mm 277203 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.

Yes, in 16 mm leather. On a 31 mm case a calf strap works every day; if you want something more, alligator.

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.
