Rolex Cellini with arab symbols

[Francisandlucy]

Hi everybody. My father, which travelled a lot for work, bought yrs ago a 18 carats gold round Rolex Cellini which gave as a present to my mum. The strap is not original anymore, but I think it's a rare model, it has the word "Cellini", the model of the watch, written in arab, and under the Rolex crown there are a palm tree and two crossing swords. Does anybody knows where does it come from and how much could cost such a model? I'm really curious to know...thanks very much, xxx
