1969 IWC Schaffhausen Ingenieur Ref.866 AD

Authenticity Guaranteed / 14-days Inspection Period / 1-year Warranty

Delivery: ca.10 days

Truly legendary vintage watch by IWC Schaffhausen. The original Ingenieur was among the very first watches designed to be truly antimagnetic and resist strong magnetic and electric fields. This particular timepiece represents the second generation of Ingenieur series and has reference 866. The updated execution also combines all the best what you can expect from a vintage watch - oversize yet still elegant 37.5 mm stainless steel case with soft iron inner case and screw-down caseback, reliable and famous "Pellaton" movement, beautiful sunburst dial, and provenance of a real tool watch.

Professionally serviced in September 2018. Technical warranty: 1 year.
