Pioneer Perpetual Calendar 42.8mm

How it wears

Wears true to its 42.8 mm case size

H. Moser & Cie Pioneer Perpetual Calendar 42.8mm measures 51 mm lug-to-lug on a 42.8 mm case, a lug-to-lug ratio of 1.19 against a database median of 1.18. That span is longer than 89% of the 7,421 watches in this database and longer than 89% of the 38 H. Moser & Cie watches listed.

A flat wrist width of 57 mm (2.24 in) or more keeps it in the balanced range, and from 68 mm (2.68 in) it starts to look compact. Below 51 mm (2.01 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
