... i think you should go for the one that made your heart beat faster 1st time you saw it. Personally, i wore an AP RO chrono for 10 years, every day, even if i had other watches i wore only on special occassions. I Don't know which bug bite me, but i went suddenly in a frenzy of buying watches.
I recently got the JLC Master compressor chrono RG. 1st JLC i ever got, and to tell u the truth, i've been loving it more n more each day. The geographic is nice, but the over busy dials tend to bore me after a while, even if i can like it in the beginning. If i were u, i would wait on that one, and come and go several times to ur AD to check it, before buying it.
The Nardin is nice, but i think its too focused on the sea concept to be an every day watch. Remember that with the rolex u had, there will always be in the back of ur mind the temptation to compare with ur Rolex.
If i were u, i'd go for the MCC. Here is a pics i took with my phone, sorry for the bad quality. Btw, the strap if really amazing, its the only watch i have that has an unscratchable strap 
keep us posted
