This is the rare 14 ct yellowgold version of the IWC Yacht Club, Ref. 1811, manufactured in 1971 with serial 198XXXX. The 36mm case made of 14ct yellowgold is in excellent condition. A very unusual combination is the gold case and the caseback made out of steel. You might think this is a service caseback, but it is not. Watch has been delivered exactly this way and is pictured in the official IWC catalogue 1972 with the description: “1811 – 14ct gold with steelback”. According to IWC this watch was first sold on May 18th, 1971 to Golay in Geneva/Switzerland. Movent is running strong with no indication for a service. Has a new gator strap (not IWC), the original IWC goldplated buckle and original IWC box.
