Hi George
If you are still happy with your CB, why not just keep it? You should consider it carefully before selling it.
I would state, if I was to keep one FPJ, it would be a Resonance. I went with 2. Generation as it is easier and more practical than 1. Gen since I wear mine a lot. Otherwise I would say Chronometre Souverain as my second favorite. I consider this watch a notch above the CB.
Some long time collectors swear by the Q but you will have to like the OCTA Automatique.
