Zenith Chronomaster Revival El Primero A3818 "Airweight Cover Girl" 37mm

How it wears

Wears larger than its 37 mm case suggests

Zenith Chronomaster Revival El Primero A3818 "Airweight Cover Girl" 37mm measures 46.9 mm lug-to-lug on a 37 mm case, a lug-to-lug ratio of 1.27 against a database median of 1.18. That span is shorter than 53% of the 8,010 watches in this database and shorter than 47% of the 59 Zenith 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 46.9 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.
