How the Captain Cook High-Tech Ceramic Diver wears

Its lugs add 6.8 mm to the 43 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 7" to 8.25" (17.8–21.0 cm); below 7" the lugs start to reach the edge of the wrist.

At 14.6 mm thick it is thicker than 91% of the 145 other dive watches we've measured, so expect it to sit tall on the wrist.

Will the Captain Cook High-Tech Ceramic Diver fit your wrist?

With a 49.8 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.

Wrist	Flat width (est.)	Fit
6"	47.2 mm	Lugs overhang
6.5"	51.2 mm	Snug, lugs near the edge
7"	55.1 mm	Ideal fit
7.5"	59.1 mm	Ideal fit
