Let's say what you have is worth 96K USD (5196j, 5127g, 5296g, WT, AC=> $15,$18,$18,$25,$20
So if you're really settled on 3940 being too small - and trying to stick to patek
1. Less coherent but more fun:
a. 5205g - (allows you to keep you other watches but a stunner)
b. 5196 - (le grande classique)
c. 5127 - (the most casual calatrava other than the 5212a)
d. WT - (doesn't speak to me - but i see the logic)
2. The statement piece, the grand classic and the daily wearer - (also if you do the 5070 you're still in the golden era)
a. 5070g (more coherent and collectable) or 5905p (more useful)
b. 5196j
c. 5127g
