Amusingly...
my wife has quite an interest in watches as well and she has a similar collection as yours. Few Rolexes, Pam 98 although her JLC is a Reverso.
She has both the 5800 and the old 5065 jumbo Aquanaut. I feel that the 5800 offers more versatility whereas any and all Aquanauts on rubber strap are too casual to be dressed up thus just a bit limited as compared to the 5800. Her small quartz aquanaut on steel bracelet hardly gets anymore wrist time since the 5800 joined us last Xmas. Having said all that, I think the 5800 gets a slight nod OVER the Aquanaut ONLY because of its versatility. Just my own two cents 
Nautilus 5800/1A or Aquanaut?
I'm a female with a keen interest in watches, mens watches for the most part. I have several Rolex, a 40MM PAM, JLC Master Ultra Thin and PP 5127R. I am considering a Nautilus 5800/1A or Aquanaut not sure 5065A, 5066A, 5165 or 5167, I'm not quite sure yet...
