Halios Seaforth GMT 40mm

How it wears

Wears true to its 40 mm case size

Halios Seaforth GMT 40mm measures 48 mm lug-to-lug on a 40 mm case, a lug-to-lug ratio of 1.20 against a database median of 1.18. That span is longer than 63% of the 8,093 watches in this database.

A flat wrist width of 54 mm (2.13 in) or more keeps it in the balanced range, and from 64 mm (2.52 in) it starts to look compact. Below 48 mm (1.89 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 12 mm thick it sits within the typical range, thicker than 46% of the watches with a listed thickness.
