They are not the best pictures I have ever looked at, really blurry.
I can tell you without a doubt that its a fake just by looking at the date. Its off somehow, wether its the size of the date window or the magnification, something is off.
The crown looks odd at the 12 0'clock. You will never see a Rolex with the hash marks appearing inbetween the prongs of the crown. and actually the crown looks bigger than it should, again with the pictures, its hard to tell for sure.
Heres a better pic of my DJ
Notice the crown up top... date magnification...
without looking at anyother pic, thats how I know its a fake.
In one of the other pictures that show the caseback, I have never seen a Rolex movement that looked like that
the lettering ROLEX Oyster perp. Datejust should be higher on the face
It even seems as though the date markers do not align correctly, but that may be the quality of the pictures
