I'm here to report that the wearability of the Aquanaut is truly outstanding, and this is something that one cannot know until they buy the watch and trim the strap to fit. Once that is done the strap ever-so-lightly makes grippy contact with each side of your wrist and there the watch stays, with no moving up-down or side to side on your wrist.
Since the strap is cut to fit you really must creep up on the fit and err on the side of one rib too big rather than risk too tight. The result is just featherlight, perfect fit, and in 24 hrs I've felt no need for any adjustment at all. Just great.
For grins I weighed mine...
While my SS SubC weighs 147 grams, the 5167 weighs in at only 76 grams. It's a difference you really feel.
I've come to view the Aquanaut as basically a Calatrava that has joined the witness protection program...
