This sounds like an 'exit' watch so it has to be something versatile and robust, literally and metaphorically.
myself, I would probably focus on a more classic and complicated Patek i.e a chronograph/perp. calendar, or a Patek world time, without this meaning that the aquanaut is not a very interesting option.
the only other alternative I would have thought for myself, as maybe I am a more flamboyant individual, is royal oak in gold (39mm - all gold or only head in gold)?
Other than that, well done, I am thinking of consolidating one day too. Would be interersted in knowing of your thoughts if eventually pull the trigger.
