The IWC Schaffhausen Iw328901 Ingenieur Automatic is widely praised for its faithful reissue of Gérald Genta's original design, featuring refined proportions, enhanced ergonomics, and excellent case and bracelet finishing with alternating brushed and polished surfaces. Owners and reviewers highlight the comfortable 40mm case size and a shortened lug-to-lug distance of 45.7mm, contributing to a wearable fit. Specific praise is given to the shimmering "grid" dial pattern and the date alignment. Some owners find the watch overpriced, citing the basic caliber and lack of micro-adjustment on the clasp, while others criticize the crown guards and bezel screw arrangement. One owner notes its accuracy rivals METAS-certified watches, and the 120-hour power reserve is also a noted feature. Overall, owners and reviewers rate the IWC Schaffhausen Iw328901 Ingenieur Automatic highly for its successful revival of a classic design with modern refinements and excellent finishing.
