How the Master Collection 39mm (2026) wears

Its lugs add 7.1 mm to the 39 mm case, close to the 7.1 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 6.5" to 7.75" (16.5–19.7 cm); below 6.5" the lugs start to reach the edge of the wrist.

At 9.4 mm thick it is slimmer than 73% of the 56 other dress watches we've measured, so it slides under a cuff more easily than most.

Will the Master Collection 39mm (2026) fit your wrist?

With a 46.1 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.

6.5"	51.2 mm	Ideal fit
7"	55.1 mm	Ideal fit
