MB&F SP One 38mm

How it wears

Wears smaller than its 38 mm case suggests

MB&F SP One 38mm measures 42 mm lug-to-lug on a 38 mm case, a lug-to-lug ratio of 1.11 against a database median of 1.18. That span is shorter than 86% of the 8,093 watches in this database and shorter than 91% of the 32 MB&F watches listed.

A flat wrist width of 47 mm (1.85 in) or more keeps it in the balanced range, and from 56 mm (2.20 in) it starts to look compact. Below 42 mm (1.65 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
