Portofino Automatic 40mm

How it wears

Wears smaller than its 40 mm case suggests

IWC Portofino Automatic 40mm measures 45 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.13 against a database median of 1.18. That span is shorter than 70% of the 7,421 watches in this database and shorter than 98% of the 42 IWC watches listed.

A flat wrist width of 50 mm (1.97 in) or more keeps it in the balanced range, and from 60 mm (2.36 in) it starts to look compact. Below 45 mm (1.77 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 9.2 mm thick it is on the slim side, thinner than 90% of the watches with a listed thickness.
