How it wears

Wears larger than its 30 mm case suggests

Seiko Discover More SUR412 30mm measures 36.3 mm lug-to-lug on a 30 mm case, a lug-to-lug ratio of 1.21 against a database median of 1.18. That span is shorter than 96% of the 7,421 watches in this database and shorter than 99% of the 390 Seiko watches listed.

A flat wrist width of 41 mm (1.61 in) or more keeps it in the balanced range, and from 49 mm (1.93 in) it starts to look compact. Below 36.3 mm (1.43 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 7.6 mm thick it is on the slim side, thinner than 96% of the watches with a listed thickness.
