Please forgive me for using this old thread, but I think my question fits here well, without creating a new topic.
I recently acquired a ref. 3536 Aquatimer. The watch's authenticity isn't in question, however I'm not sure if someone "completed" the package with a phony guarantee card. The card is obviously blank, so it could come from anywhere. When I compare the hologram and the print with others I could find on the net, I not sure if the card is genuine. The watch is from 2003, so I guess it's possible, that IWC had different suppliers over the years and certainly different batches made what could explain slight differences.
Here are some pictures of the card:






I would really appreciate your input and this one.
Thank you very much.
And a picture of the watch, as we are in a watch-forum :)
