Le Régulateur II 43mm

How it wears

Wears true to its 43 mm case size

Louis Erard x Vianney Halter Le Régulateur II 43mm measures 49.6 mm lug-to-lug on a 43 mm case, a lug-to-lug ratio of 1.15 against a database median of 1.18. That span is longer than 80% of the 7,421 watches in this database.

A flat wrist width of 56 mm (2.20 in) or more keeps it in the balanced range, and from 67 mm (2.64 in) it starts to look compact. Below 49.6 mm (1.95 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 10.95 mm thick it sits within the typical range, thicker than 26% of the watches with a listed thickness.
