Master Ultra Thin Moon 39mm
Q1368430
How it wears
Wears true to its 39 mm case size
JLC Master Ultra Thin Moon 39mm measures 46.7 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.20 against a database median of 1.18. That span is shorter than 55% of the 7,421 watches in this database and shorter than 32% of the 25 JLC watches listed.
A flat wrist width of 52 mm (2.05 in) or more keeps it in the balanced range, and from 63 mm (2.48 in) it starts to look compact. Below 46.7 mm (1.84 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
