Grand Complications Perpetual Calendar 39mm

How it wears

Wears true to its 39 mm case size

Patek Philippe Grand Complications Perpetual Calendar 39mm measures 46.5 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.19 against a database median of 1.18. That span is shorter than 56% of the 7,413 watches in this database and shorter than 51% of the 79 Patek Philippe watches listed.

A flat wrist width of 52 mm (2.05 in) or more keeps it in the balanced range, and from 62 mm (2.44 in) it starts to look compact. Below 46.5 mm (1.83 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
