Newbie with a Rolex I need to ID

[codmac]

Hi all... just joined this forum, looking for answers... :)

My grandfather just moved to France and gave away most of his things! I scored big because I got some nice furniture and kitchen stuff, etc...

He also gave me a Rolex watch that seems never to have been used! But personally, I don't exactly like the style. It also seems to be from china or something.

Here is a picture, I want to know if anyone can recognize it, and tell me if its real? Plus, it looks like it has diamonds in it... Could anyone tell me the approximate value? Thanks everyone!
