Reverso One Duetto 20mm

How it wears

Wears larger than its 20 mm case suggests

Jaeger-LeCoultre Reverso One Duetto 20mm measures 40.1 mm lug-to-lug on a 20 mm case, a lug-to-lug ratio of 2.00 against a database median of 1.18. That span is shorter than 92% of the 8,010 watches in this database and shorter than 76% of the 75 Jaeger-LeCoultre watches listed.

A flat wrist width of 45 mm (1.77 in) or more keeps it in the balanced range, and from 54 mm (2.13 in) it starts to look compact. Below 40.1 mm (1.58 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
