Reef GMT 42mm Automatic COSC 300M

How it wears

Wears smaller than its 42 mm case suggests

Formex Reef GMT 42mm Automatic COSC 300M measures 47 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.12 against a database median of 1.18. That span is shorter than 47% of the 7,413 watches in this database and shorter than 13% of the 67 Formex watches listed.

A flat wrist width of 53 mm (2.09 in) or more keeps it in the balanced range, and from 63 mm (2.48 in) it starts to look compact. Below 47 mm (1.85 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 11.4 mm thick it sits within the typical range, thicker than 32% of the watches with a listed thickness.
