Seiko Prospex Street Series Urban Safari SRPE29K1 & SRPE31K1 40mm

How it wears

Wears smaller than its 40 mm case suggests

Seiko Prospex Street Series Urban Safari SRPE29K1 & SRPE31K1 40mm measures 44 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.10 against a database median of 1.18. That span is shorter than 78% of the 8,010 watches in this database and shorter than 88% of the 390 Seiko watches listed.

A flat wrist width of 49 mm (1.93 in) or more keeps it in the balanced range, and from 59 mm (2.32 in) it starts to look compact. Below 44 mm (1.73 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
