Grand Seiko Hi-Beat GMT Yukigesho 39.5mm
SBGJ271
How it wears
Wears true to its 39.5 mm case size
Grand Seiko Hi-Beat GMT Yukigesho 39.5mm measures 46.9 mm lug-to-lug on a 39.5 mm case, a lug-to-lug ratio of 1.19 against a database median of 1.18. That span is shorter than 53% of the 8,010 watches in this database and shorter than 44% of the 232 Grand Seiko 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 46.9 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.
At 14.1 mm thick it is on the thicker side, thicker than 84% of the watches with a listed thickness.
