Heritage Perpetual Calendar 42mm

How it wears

Wears smaller than its 42 mm case suggests

H. Moser & Cie Heritage Perpetual Calendar 42mm measures 47 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.12 against a database median of 1.18. That span is shorter than 47% of the 7,413 watches in this database and shorter than 68% of the 38 H. Moser & Cie watches listed.

A flat wrist width of 53 mm (2.09 in) or more keeps it in the balanced range, and from 63 mm (2.48 in) it starts to look compact. Below 47 mm (1.85 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
