Notes

 The IWC Ingenieur SL Automatic was produced in less than 600 examples between 1976-1984. The present example is being offered with the original box and certificate in all original condition. Examples entirely cased in 18K yellow gold, such as the present lot, were only produced for two years, making them amongst the most sought after watches from the Ingenieur family
