This is an awesome vintage IWC Ingenieur. A reference 666 with a pretty sweet no lume, no date configuration, now sporting an elegantly aged champagne dial. It house the 853 caliber which was just a dream to work on and service. Being in the field of engineering my favorite part of this watch is the fact that it was developed to be worn by engineers back in the day, designed with a primary focus on anti magnetism. The International Watch Co’s Ingenieur was their version of Rolex’s Milgauss and Omega’s Railmaster. The amagnetic watch is housed in a cool sized 37mm steel case, which gives the watch a real presence on the wrist. The watch is all original and in great condition. The movement has just been serviced and runs great. The dial has a lovely patina, the case is unpolished and in great condition, the bottom right lug has a small knick.
