Roadmaster M Model A 41mm

How it wears

Wears true to its 41 mm case size

Ball Roadmaster M Model A 41mm measures 48.5 mm lug-to-lug on a 41 mm case, a lug-to-lug ratio of 1.18 against a database median of 1.18. That span is longer than 70% of the 7,413 watches in this database and longer than 48% of the 222 Ball watches listed.

A flat wrist width of 54 mm (2.13 in) or more keeps it in the balanced range, and from 65 mm (2.56 in) it starts to look compact. Below 48.5 mm (1.91 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 15.2 mm thick it is on the thicker side, thicker than 94% of the watches with a listed thickness.
