Nautilus Perpetual Calendar 5740 40mm

How it wears

Wears smaller than its 40 mm case suggests

Patek Philippe Nautilus Perpetual Calendar 5740 40mm measures 44 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.10 against a database median of 1.18. That span is shorter than 78% of the 7,413 watches in this database and shorter than 75% of the 79 Patek Philippe watches listed.

A flat wrist width of 49 mm (1.93 in) or more keeps it in the balanced range, and from 59 mm (2.32 in) it starts to look compact. Below 44 mm (1.73 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 8.42 mm thick it is on the slim side, thinner than 93% of the watches with a listed thickness.
