In life, is it's too good to be true, it usually is. I'd consider reporting this guy to ebay's fraud patrol.
I know for sure it's fake. Nobody has a chronomat breitling with $3k diamond bezel and no papers.....
With all the bullshit going on with Ebay, they don't have time to police all this crap. He states right in his description that he has no papers and doesn't know it's value.
I just bought a few things on Ebay for halloween. Let me tell you, you have to be on your game when dealing with these guys. They will pull a fast one on you every chance they can.
