Firstly, welcome to WatchFreeks. I hope you will take a moment to introduce yourself when you have a chance here:

Secondly, if you have any question as to the authenticity of a high dollar watch, THE ONLY WAY to make sure you are not getting ripped off is by taking it to an Authorized Dealer, or an trusted watchmaker. Box and papers can be forged just as much as watches, serial numbers can be faked, and even sellers can come up with fake references. Asking a bunch of strangers on a forum if your low resolution photo of a watch (that happens to be a heavily counterfeited model) won't help you get answers. Chances are if you have to ask, then you won't like the answer.
