How would i go about finding the worth of a rolex watch?

The watch is an Oyster perpetual day date. it is authentic, but for some reason i can't find a site that will tell the the average worth of it. it is 18k yellow gold, 32 mm, no jewels on it, no numbers or roman numerals, just dashes. it is number 8828, serial number 8570f. can someone please help me out? thanks very much for your time.|||You should try and find a local jeweler or three that will appraise the piece for you. this is the best way to find out how much it's worth. Although off the top of my head I'd say somewhere north of $10,000, depending on the condition.|||have you looked on ebay?
