Me and my friend recieved this Rolex as gift. We are unsure if it is really a Rolex, and if it is real, what it is worth. The casing around the face is stainless steel, with gold colored decorative ridges. The case is 2cm or 13/16 of an inch in diameter. The marking on the has a number 68288 and says Rolex Swiss. It appears to be a wind up watch. The face of the watch changes colors.
