How the Cosmograph Daytona wears

Its lugs add 6.5 mm to the 40 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 6.5" to 7.75" (16.5–19.7 cm); below 6.5" the lugs start to reach the edge of the wrist.

At 12.2 mm thick it is slimmer than 83% of the 47 other chronograph watches we've measured, so it slides under a cuff more easily than most.

Its 20 mm lug width is one of the most common strap sizes; 186 other watches here share it, so aftermarket straps are easy to find.

Will the Cosmograph Daytona fit your wrist?

With a 46.5 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
