Captain Cook Automatic 39mm

Its lugs add 6.5 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 7.5" (16.5–19.1 cm); below 6.5" the lugs start to reach the edge of the wrist.

At 12 mm thick it is slimmer than 82% of the 79 other dive watches we've measured, so it slides under a cuff more easily than most.
