When you look for EBay Rolex Watches, you have to start with their website. You will find a large collection of Rolex watches on it; many of them would be real. It is the others that you have to look out for to see if they are fakes. Sometimes, the owner himself may not know he has a fake.
Ask for some good photographs from the seller, they should be from every angle. They might be on the listing itself. What you are looking for is the serial number, the gems, the dial etc. Does the serial number match the type of watch? Do the gems look real? Does the dial have any blemishes?
