Real or Fake? Datejust Champagne Diamond Dial

[pjwaltz414]

Hey everyone,
Im a total noobie when it comes to the world of luxury watches, but I've certainly developed an interest recently. Now, I'm on the hunt to purchase my first Rolex, but of course, I'll do whatever I can to avoid purchasing a fake. I am aware that there are some detailed fakes out there that could easily fool noobies like myself; so I figured I'd post the photos in here to get some verification before I contact the private seller (I can also request more detailed photos if you guys suggest I do so).
A few things that stuck out to me: 1:There are two engraving marks on the back of the watch itself in the top right and bottom left corners, is this normal? 2: The Rolex symbol on the band looks a little off, but could it just be a bad aftermarket band? 3:The paperwork in the photo appears to be French. Do they make fake paperwork you can buy from other countries?

PS. If you guys could give me some pointers informing me what to look out for or to help identify a Rolex as real or fake Id very much appreciate it!

Thanks!
