Fake and Real Rolex

[fredswatch]

Which is the real rolex and which is the fake

The one on the right is the fake..hard to tell

[therolexkid]

Yes, very difficult to tell which is the real one, but always is from a picture or vid, when youve got it in your hands then its really easy..but getting more difficult, but if in doubt then just open the back...most fakes use a battery and the small percentage of fakes that don't use a battery have a really cheap movement. But there are some good ones that have a good movement and then in that case the movement is not signed rolex.

I'm afraid I would be one of those people that got burned on a deal like this, because I would have no idea how to tell which is which. So real Rolex watches do NOT have a battery?
