The Collectibles Reverso Small Seconds 21mm

How it wears

Wears larger than its 21 mm case suggests

Jaeger-LeCoultre The Collectibles Reverso Small Seconds 21mm measures 39 mm lug-to-lug on a 21 mm case, a lug-to-lug ratio of 1.86 against a database median of 1.18. That span is shorter than 93% of the 7,421 watches in this database and shorter than 89% of the 54 Jaeger-LeCoultre watches listed.

A flat wrist width of 44 mm (1.73 in) or more keeps it in the balanced range, and from 52 mm (2.05 in) it starts to look compact. Below 39 mm (1.54 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
