Patek Philippe

I'm a bit biased,but >>>>(lot of pics)

I would go on a 3712 or a 5110.
The Nautilus is an elegant sportwatch ,and the 3712 or the new ref 5712 is stunning ,with a beautiful dial,and as I know that you love Panerai ,I'm sure you have the "culture" of the dial.
The 5110 is a wathc to dream...You see the dial ,you have the feeling you're traveling around the world.
This is my fav Patek.
Here are some pics for you.

BUT You may have another option ,and IMO,one of the nicest Calatrava ever made...The 5196P:

Hope it will help you!
