Airain Type 20 x seconde/seconde Up In The Air 39mm

How it wears

Wears larger than its 39 mm case suggests

Airain Type 20 x seconde/seconde Up In The Air 39mm measures 47.7 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.22 against a database median of 1.18. That span is longer than 60% of the 8,010 watches in this database.

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 47.7 mm (1.88 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 10.85 mm thick it sits within the typical range, thicker than 25% of the watches with a listed thickness.
