Louis Erard Excellence Régulateur Grand Feu Enamel 39mm

How it wears

Wears true to its 39 mm case size

Louis Erard Excellence Régulateur Grand Feu Enamel 39mm measures 45.9 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.18 against a database median of 1.18. That span is shorter than 66% of the 8,093 watches in this database and shorter than 62% of the 29 Louis Erard watches listed.

A flat wrist width of 51 mm (2.01 in) or more keeps it in the balanced range, and from 62 mm (2.44 in) it starts to look compact. Below 45.9 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.
