Can this be moved to the "real or fake thread" Speedmaster Schumacher genuine or fake?

Edit: sorry i did not see the other thread, can this be moved.
I'm looking at buying this watch, but it is not coming with papers. I have not viewed yet but I will be going to see it this weekend. The seller says that he can not see any reference numbers on the back as they have been worn off. He has a receipt for service 3 months ago but it has no details on it. The 2 straps it is coming with do not look genuine either.
Could you tell from the picture of the case back if it is genuine or fake?

Sorry i was having difficulty linking pictures, they are added now.

Thanks for all the replys, I purchased the watch at the weekend and I am delighted with it.
