IWC Extremely rare Porsche Design compass watch Yellow Gold like Ref.

I'm further reducing my IWC collection and selling my Porsche Design compass watches.

Here is a genuine extremely rare Porsche Design Kompassuhr, like Ref. 3510 but in Yellow Gold with original box. All case parts including the backs and the bracelet are made from solid Yellow Gold. The case dimensions are 38 mm * 13 mm without crown. The watch is in mint, the box in fair condition.

The watch is located in Germany.
