They actually exist, legitimate individuals! An individual discovered this Rolex Deepsea Sea-Dweller when he was visiting Amsterdam last Saturday. He had the watch checked by a goldsmith to see whether it was a certifiable Rolex. It is.
If you can evidence it is yours, showing your Rolex documentation (guarantee card, with the chronic number on it) you can get it back from this person. In this way, in the event that you are the person who lost his Rolex, it is just an email away.
Kudos to the legitimate locater of the watch for welcoming it under the consideration on the no.1 Dutch site, (lost & discovered area). On account of MaPaLu @ for the notification.
