IWC Big Pilot Perpetual Calendar Tourbillon Le Petit Prince 46.5mm

How it wears

Wears true to its 46.5 mm case size

IWC Big Pilot Perpetual Calendar Tourbillon Le Petit Prince 46.5mm measures 56 mm lug-to-lug on a 46.5 mm case, a lug-to-lug ratio of 1.20 against a database median of 1.18. That span is longer than 99% of the 8,093 watches in this database and longer than 93% of the 43 IWC watches listed.

A flat wrist width of 63 mm (2.48 in) or more keeps it in the balanced range, and from 75 mm (2.95 in) it starts to look compact. Below 56 mm (2.20 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
