How it wears

Wears true to its 43.8 mm case size

Grand Seiko Masterpiece Kodo Constant-force Tourbillon 43.8mm measures 50.6 mm lug-to-lug on a 43.8 mm case, a lug-to-lug ratio of 1.16 against a database median of 1.18. That span is longer than 88% of the 7,421 watches in this database and longer than 85% of the 202 Grand Seiko watches listed.

A flat wrist width of 57 mm (2.24 in) or more keeps it in the balanced range, and from 68 mm (2.68 in) it starts to look compact. Below 50.6 mm (1.99 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
