Borealis Adraga Steel 39.5mm

How it wears

Wears true to its 39.5 mm case size

Borealis Adraga Steel 39.5mm measures 47.5 mm lug-to-lug on a 39.5 mm case, a lug-to-lug ratio of 1.20 against a database median of 1.18. That span is longer than 57% of the 8,010 watches in this database and longer than 32% of the 25 Borealis 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 47.5 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 12 mm thick it sits within the typical range, thicker than 46% of the watches with a listed thickness.
