Formex Essence 39mm Blue Agate

How it wears

Wears true to its 39 mm case size

Formex Essence 39mm Blue Agate measures 45 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.15 against a database median of 1.18. That span is shorter than 70% of the 8,010 watches in this database and shorter than 88% of the 67 Formex watches listed.

A flat wrist width of 50 mm (1.97 in) or more keeps it in the balanced range, and from 60 mm (2.36 in) it starts to look compact. Below 45 mm (1.77 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 mm thick it is on the slim side, thinner than 82% of the watches with a listed thickness.
