How it wears

Wears true to its 29.9 mm case size

Seiko Discover More SUR427 29.9mm measures 35.6 mm lug-to-lug on a 29.9 mm case, a lug-to-lug ratio of 1.19 against a database median of 1.18. That span is shorter than 96% of the 7,413 watches in this database and shorter than 99% of the 390 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 35.6 mm (1.40 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 7.5 mm thick it is on the slim side, thinner than 96% of the watches with a listed thickness.
