Yema Navygraf Marine Nationale GMT 39mm

How it wears

Wears true to its 39 mm case size

Yema Navygraf Marine Nationale GMT 39mm measures 47 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.21 against a database median of 1.18. That span is shorter than 47% of the 8,093 watches in this database and shorter than 14% of the 29 Yema watches listed.

A flat wrist width of 53 mm (2.09 in) or more keeps it in the balanced range, and from 63 mm (2.48 in) it starts to look compact. Below 47 mm (1.85 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
