Reverso Classic Monoface 21mm

How it wears

Wears larger than its 21 mm case suggests

JLC Reverso Classic Monoface 21mm measures 35.78 mm lug-to-lug on a 21 mm case, a lug-to-lug ratio of 1.70 against a database median of 1.18. That span is shorter than 96% of the 7,413 watches in this database and shorter than 88% of the 25 JLC watches listed.

A flat wrist width of 40 mm (1.57 in) or more keeps it in the balanced range, and from 48 mm (1.89 in) it starts to look compact. Below 35.78 mm (1.41 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
