Ever wonder the difference in movement and marking of Tudor with Rolex even though they are produced by the same company.
Here are some pictures that I think it will be useful to all watch collectors.
Tudor Prince Oyster Date (Rotor Self Winding- Automatic in another word)

Typical Rolex Case

Inside of the case is stamped with Tudor instead of Rolex if it is a Rolex but then again I have seen some with Rolex Stamp on it as well.

A definite distinct different in the movement with Tudor marking clearly stamped.
I hope all these information are useful to all watch collectors, I do not know what you collectors are interested, please do advise me and I see what I can do for you. Remember Knowledge is Power and let's share our knowledge and there is no point bring it to the grave with you.
