Heritage Collection 27.8mm

How it wears

Wears true to its 27.8 mm case size

Grand Seiko Heritage Collection 27.8mm measures 33.5 mm lug-to-lug on a 27.8 mm case, a lug-to-lug ratio of 1.21 against a database median of 1.18. That span is shorter than 97% of the 8,010 watches in this database and shorter than 97% of the 232 Grand Seiko watches listed.

A flat wrist width of 38 mm (1.50 in) or more keeps it in the balanced range, and from 45 mm (1.77 in) it starts to look compact. Below 33.5 mm (1.32 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 11.2 mm thick it sits within the typical range, thicker than 31% of the watches with a listed thickness.
