Trainmaster MSF Humanity 38mm

How it wears

Wears true to its 38 mm case size

Ball Trainmaster MSF Humanity 38mm measures 45.5 mm lug-to-lug on a 38 mm case, a lug-to-lug ratio of 1.20 against a database median of 1.18. That span is shorter than 68% of the 7,413 watches in this database and shorter than 94% of the 222 Ball watches listed.

A flat wrist width of 51 mm (2.01 in) or more keeps it in the balanced range, and from 61 mm (2.40 in) it starts to look compact. Below 45.5 mm (1.79 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 10.35 mm thick it is on the slim side, thinner than 82% of the watches with a listed thickness.
