El Primero A3817 37mm
A3817
How it wears
Wears larger than its 37 mm case suggests
Zenith El Primero A3817 37mm measures 47 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 47% of the 7,413 watches in this database and shorter than 20% 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 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.
