Heritage Collection Self-winding with manual-winding 28.7mm

How it wears

Wears larger than its 28.7 mm case suggests

Grand Seiko Heritage Collection Self-winding with manual-winding 28.7mm measures 35.1 mm lug-to-lug on a 28.7 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 96% of the 232 Grand Seiko watches listed.

A flat wrist width of 39 mm (1.54 in) or more keeps it in the balanced range, and from 47 mm (1.85 in) it starts to look compact. Below 35.1 mm (1.38 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 10.9 mm thick it sits within the typical range, thicker than 26% of the watches with a listed thickness.
