This 1968 IWC Ingenieur Ref. 866 is a highly refined and sought-after example of the iconic Ingenieur line, featuring an oversized solid 18K yellow gold case, never polished, measuring 37.5 mm and offering strong presence with timeless elegance. The original champagne dial, beautifully preserved, showcases applied faceted gilt baton hour markers, gilt baton hands with luminous inserts, and a framed date window at 3 o’clock. The dial remains untouched, retaining its authentic character and patina. At its heart beats the acclaimed IWC Caliber 8541, an automatic movement with 25 jewels and the innovative Pellaton winding system, celebrated for its reliability, precision and mechanical sophistication. The movement is clean and fully operational. A remarkable piece for discerning collectors seeking elegance, technical excellence and historical value from one of Switzerland’s most prestigious manufactures.
