Heritage Collection 42mm

How it wears

Wears smaller than its 42 mm case suggests

Grand Seiko Heritage Collection 42mm measures 47.9 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.14 against a database median of 1.18. That span is longer than 62% of the 7,413 watches in this database and longer than 69% of the 202 Grand Seiko watches listed.

A flat wrist width of 54 mm (2.13 in) or more keeps it in the balanced range, and from 64 mm (2.52 in) it starts to look compact. Below 47.9 mm (1.89 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
