Prospex The Black Series Limited Edition 45mm

How it wears

Wears true to its 45 mm case size

Seiko Prospex The Black Series Limited Edition 45mm measures 52.6 mm lug-to-lug on a 45 mm case, a lug-to-lug ratio of 1.17 against a database median of 1.18. That span is longer than 96% of the 7,421 watches in this database and longer than 99% of the 390 Seiko watches listed.

A flat wrist width of 59 mm (2.32 in) or more keeps it in the balanced range, and from 71 mm (2.80 in) it starts to look compact. Below 52.6 mm (2.07 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 12.9 mm thick it sits within the typical range, thicker than 60% of the watches with a listed thickness.
