The IWC Automatic reference R817AD is known to only a few collectors; this model is not listed in the relevant literature. It has a three-piece case with a screw back, which is much more elaborately crafted than that of the Yacht Club. While the bezel is still comparable, the middle part of the case has elegant lugs that are satin-finished on the sides and top. This model was available both in 18 K yellow gold and stainless steel. The production time was about two years, the exact number of produced are not known. IWC estimates that a total of 1,000 to 2,000 pieces were produced.
