Grand Seiko Heritage 62GS Spring Drive 40mm

How it wears

Wears true to its 40 mm case size

Grand Seiko Heritage 62GS Spring Drive 40mm measures 47 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.18 against a database median of 1.18. That span is shorter than 46% of the 8,010 watches in this database and shorter than 33% 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 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.

At 12.8 mm thick it sits within the typical range, thicker than 60% of the watches with a listed thickness.
