Girard-Perregaux 1966 WW.TC 40mm

How it wears

Wears true to its 40 mm case size

Girard-Perregaux 1966 WW.TC 40mm measures 46 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.15 against a database median of 1.18. That span is shorter than 60% of the 8,093 watches in this database and shorter than 10% of the 10 Girard-Perregaux 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 mm (1.81 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 12 mm thick it sits within the typical range, thicker than 46% of the watches with a listed thickness.
