Engineer II Moon Phase Chronometer 41mm

How it wears

Wears true to its 41 mm case size

Ball Engineer II Moon Phase Chronometer 41mm measures 47.6 mm lug-to-lug on a 41 mm case, a lug-to-lug ratio of 1.16 against a database median of 1.18. That span is longer than 59% of the 7,421 watches in this database and longer than 23% 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 64 mm (2.52 in) it starts to look compact. Below 47.6 mm (1.87 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 13.95 mm thick it is on the thicker side, thicker than 80% of the watches with a listed thickness.
