Your pros and cons list appear to be fairly accurate.
I only have sporty models but dont regret one bit ditching Rolex, which brought unwanted attraction on the odd occassion - though def wise to keep one for more testing activities where ones PP could get a knock!! I would prefer a battle scarred Rolex then a PP!
I wouldnt say my Aquanaut or Nautlius is delicate - just simply it would not wear a ding or a scratch as well as a sporty Rolex as generally they look more elegant and better finished
Maybe Martyn can chime in since he has a dress watch PP which if I remember rightly is what you are looking for.
