Editor's Notes

IWC SCHAFFHAUSEN delved into the archives to engineer this 40mm 'Ingenieur' - it's the model from the line most similar to the original 1955 watch. Housed in polished red gold, it's set with a handsome slate-grey dial which sits beneath a convex scratch-resistant sapphire crystal - the gentle curvature is a call back to vintage timepieces. Manufactured at the horologist's HQ in Switzerland, it's calibrated with a 35111 self-winding automatic movement with an ample 42-hour power reserve.
