IWC Portofino Handwound Eight Days 45mm

How it wears

Wears smaller than its 45 mm case suggests

IWC Portofino Handwound Eight Days 45mm measures 51.2 mm lug-to-lug on a 45 mm case, a lug-to-lug ratio of 1.14 against a database median of 1.18. That span is longer than 91% of the 8,054 watches in this database and longer than 62% of the 42 IWC watches listed.

A flat wrist width of 57 mm (2.24 in) or more keeps it in the balanced range, and from 69 mm (2.72 in) it starts to look compact. Below 51.2 mm (2.02 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
