Trainmaster Eternity Ladies 31mm

How it wears

Wears true to its 31 mm case size

Ball Trainmaster Eternity Ladies 31mm measures 36 mm lug-to-lug on a 31 mm case, a lug-to-lug ratio of 1.16 against a database median of 1.18. That span is shorter than 96% of the 7,413 watches in this database and shorter than 99% of the 222 Ball watches listed.

A flat wrist width of 40 mm (1.57 in) or more keeps it in the balanced range, and from 48 mm (1.89 in) it starts to look compact. Below 36 mm (1.42 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.
