Excalibur Chronograph 42

How it wears

Wears true to its 42 mm case size

Roger Dubuis Excalibur Chronograph 42 measures 49.3 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.17 against a database median of 1.18. That span is longer than 77% of the 7,413 watches in this database.

A flat wrist width of 55 mm (2.17 in) or more keeps it in the balanced range, and from 66 mm (2.60 in) it starts to look compact. Below 49.3 mm (1.94 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 12.5 mm thick it sits within the typical range, thicker than 54% of the watches with a listed thickness.
