How the Master Collection 30mm (2026) wears

Its lugs add 6.8 mm to the 30 mm case, close to the 7 mm typical across the almanac, so its diameter is a fair guide to how it wears.

On our fit model it sits best on wrists from 5.5" to 6" (14.0–15.2 cm).

At 9.1 mm thick it is slimmer than 68% of the 118 other dress watches we've measured, so it slides under a cuff more easily than most.

Will the Master Collection 30mm (2026) fit your wrist?

With a 36.8 mm lug-to-lug, here is how it wears across common wrist sizes. We estimate the flat top of each wrist from its circumference; measure yours for a closer answer in the fit finder.
