fake Tudor warranty certificates

[wizbang]

It seems as "vintage" watches become more popular different types of Warranty certificates are popping up. I am no expert but it seems Tudors certificates are vastly different from watch to watch and era to era...is there a place where these can be authenticated, I bought a 79090 (88 model)and It came with papers...I have no idea if they are real(the papers) Is there any way to research this. I bought from a member of this forum and am sure he is 150% honest, but I wonder if even he can distinguish real from fake, we have no frame of reference to judge these by. The Watch is legit, and pristine...save for some tobacco discoloring ariound the acrylic's edges, which I kind of like.
