During the eighties, IWC was represented in Belgium by an importer who was crazy about IWC and about cycling, so he could combine both of his passions and sponsored a cycling team. Here is a picture of Patrick Sercu in 1981 , riding for the IWC/IMEX team.
I like the writing on the back of the card ; IWC watches, designed and created to be the BEST OF THE WORLD.
I think they still do ;)
