IWC Porsche Design Catalogues

I am aware of four IWC Porsche Design Catalogues, 1989, 1991, 1993, 1995. The 1993 was available on its own and in a slip case also containing the 1993 IWC catalogue. If you know of other years please let me know on;

The table below shows the reference numbers in the respective catalogues and a link to an image of each watch. Porsche Design also had their own reference numbers for each watch.
