Grand Seiko Heritage Mechanical Hi-Beat 36000 GMT 40mm

How it wears

Wears true to its 40 mm case size

Grand Seiko Heritage Mechanical Hi-Beat 36000 GMT 40mm measures 46.2 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.16 against a database median of 1.18. That span is shorter than 59% of the 8,054 watches in this database and shorter than 53% of the 232 Grand Seiko watches listed.

A flat wrist width of 52 mm (2.05 in) or more keeps it in the balanced range, and from 62 mm (2.44 in) it starts to look compact. Below 46.2 mm (1.82 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 13.3 mm thick it sits within the typical range, thicker than 71% of the watches with a listed thickness.
