Hey folks for sale is my IWC Ingenieur, which with the serial number 13977xx is one of the first early versions of this model. The watch is in a good (unpolished?) condition. I cannot say when it was serviced the last time but it is keeping the time without any issues. Caliber 852 Ref. 666a ~ 36,5mm Gay Freres bracelet with certina clasp (watch can be bought without the bracelet) I would like to have 4000€ obo. Don’t be shy to talk with me about the price. Since this model is rarely offered, it is difficult for me to set a suitable price. I accept bank transfer or PayPal (fees at the buyers cost). best Oli
