Real or fake Rolex?

[thewall13ap]

I am very close to pulling the trigger on a blue dial datejust on Ebay but have never bought from Ebay before, so I am trying to be very careful. The watch appears to be in great shape, and the seller has 100% rating and has been very helpful answering my questions. I just want to make sure there is nothing glaringly fake about this watch, as it appears to be in such great condition (although there is normal wear and tear and microscratches). I also want to make sure that the jubilee bracelet is consistent and authentic. What do you guys think? The pictures are attached to this post and he also posted a video:
