Engineer Hydrocarbon AeroGMT Sled Driver 42mm

How it wears

Wears larger than its 42 mm case suggests

Ball Engineer Hydrocarbon AeroGMT Sled Driver 42mm measures 54 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.29 against a database median of 1.18. That span is longer than 98% of the 7,421 watches in this database and longer than 95% of the 222 Ball watches listed.

A flat wrist width of 60 mm (2.36 in) or more keeps it in the balanced range, and from 72 mm (2.83 in) it starts to look compact. Below 54 mm (2.13 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 13.85 mm thick it is on the thicker side, thicker than 79% of the watches with a listed thickness.
