Ingenieur Automatic 40
IW328904
How it wears
Wears smaller than its 40 mm case suggests
IWC Ingenieur Automatic 40 measures 45.7 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.14 against a database median of 1.18. That span is shorter than 67% of the 7,413 watches in this database and shorter than 81% of the 42 IWC watches listed.
A flat wrist width of 51 mm (2.01 in) or more keeps it in the balanced range, and from 61 mm (2.40 in) it starts to look compact. Below 45.7 mm (1.80 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
At 10.8 mm thick it is on the slim side, thinner than 77% of the watches with a listed thickness.
