Grand Seiko Heritage Collection 28.9mm

How it wears

Wears larger than its 28.9 mm case suggests

Grand Seiko Heritage Collection 28.9mm measures 35.4 mm lug-to-lug on a 28.9 mm case, a lug-to-lug ratio of 1.22 against a database median of 1.18. That span is shorter than 97% of the 8,010 watches in this database and shorter than 95% of the 232 Grand Seiko watches listed.

A flat wrist width of 40 mm (1.57 in) or more keeps it in the balanced range, and from 48 mm (1.89 in) it starts to look compact. Below 35.4 mm (1.39 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 8.7 mm thick it is on the slim side, thinner than 90% of the watches with a listed thickness.
