PrimaLuna Moonphase 30.5mm

How it wears

Wears true to its 30.5 mm case size

Longines PrimaLuna Moonphase 30.5mm measures 36.8 mm lug-to-lug on a 30.5 mm case, a lug-to-lug ratio of 1.21 against a database median of 1.18. That span is shorter than 96% of the 7,413 watches in this database and shorter than 79% of the 495 Longines watches listed.

A flat wrist width of 41 mm (1.61 in) or more keeps it in the balanced range, and from 50 mm (1.97 in) it starts to look compact. Below 36.8 mm (1.45 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 9.3 mm thick it is on the slim side, thinner than 90% of the watches with a listed thickness.
