Submariner help, real or fake

[chuckblocker]

Hi,

I am being offered this watch for 5500, some room to play in there. The problem is that I have to fly to see it in person and i only have a bunch of pictures. The watch comes alone, without any box, papers or accessories. This is what has me worried.

Would the only way to be sure of it's authenticity is removing the back? I have an idea of what the movement is supposed to look like on a real one so I'd have fewer problems spotting it that way but don't know if seller would agree to it.

Let me know what you think, only pictures I have. Seems to be from August 2006, correct me if I am wrong.

Thanks in advance for any help :) Would love to own it if is legitimate.
