Iwc mark xvi on eBay, how to check in it's legitimate?

hi all,

Wondering how to check if a certain watch on eBay is legitimate.

Below the link

Thoughts anyone?

Thanks,

Murk

Even if it's true IWC you never know where it comes from.
Anyway we're non-commercial here so it is not legitimate to discuss ebay offers here.
The seller claims that it's in excellent condition which is a lie if you look at the pics. I'd keep my hands off but hey, we're not discussing that here...

Allright, thanks, I was not aware of the rules on Forum posts, so apologies for that. Thanks for the help anyway.
