don't mess about. take it to a Rolex dealer and send it back to London to Rolex who will give you a price. I presume it has cost you nothing but assuming it's a Date or Date-Just what's the rrp on a new one? Rolex will give you a date of manufacture, a service and a guarantee. Might be £2k or less (or more). Only you will know if it has special memories or it could be an heirloom. Someone on here will know a bit more about a new dial etc
