Master Collection Moonphase 42mm
L2.919.4.92.6
How it wears
Wears true to its 42 mm case size
Longines Master Collection Moonphase 42mm measures 49.7 mm lug-to-lug on a 42 mm case, a lug-to-lug ratio of 1.18 against a database median of 1.18. That span is longer than 81% of the 7,413 watches in this database and longer than 84% of the 495 Longines watches listed.
A flat wrist width of 56 mm (2.20 in) or more keeps it in the balanced range, and from 67 mm (2.64 in) it starts to look compact. Below 49.7 mm (1.96 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 11.2 mm thick it sits within the typical range, thicker than 29% of the watches with a listed thickness.

Fit reference
Fills most of the wrist for a bold, sporty fit; lug shape and end links matter.
