Roadmaster TMT (40mm Celsius scale)

How it wears

Wears true to its 40 mm case size

Ball Roadmaster TMT (40mm Celsius scale) measures 47 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.18 against a database median of 1.18. That span is shorter than 47% of the 7,413 watches in this database and shorter than 77% of the 222 Ball watches listed.

A flat wrist width of 53 mm (2.09 in) or more keeps it in the balanced range, and from 63 mm (2.48 in) it starts to look compact. Below 47 mm (1.85 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 13 mm thick it sits within the typical range, thicker than 62% of the watches with a listed thickness.
