Fireman 2-Tone 31mm

How it wears

Wears larger than its 31 mm case suggests

Ball Fireman 2-Tone 31mm measures 37.5 mm lug-to-lug on a 31 mm case, a lug-to-lug ratio of 1.21 against a database median of 1.18. That span is shorter than 95% of the 7,421 watches in this database and shorter than 99% of the 222 Ball watches listed.

A flat wrist width of 42 mm (1.65 in) or more keeps it in the balanced range, and from 50 mm (1.97 in) it starts to look compact. Below 37.5 mm (1.48 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 10.1 mm thick it is on the slim side, thinner than 84% of the watches with a listed thickness.
