Good to hear you've returned to the dark side, the more the merrier. The 1950 44mm cases are really unique and much more interesting than many PAMs IMHO. But they are big and heavy. The 351 should be a winner if its lighter. My 312 is one of my current favourites and on heavy rotation. People moaning about the movement makes me laugh , I might spend 1 percent of my time looking at the watches underside , it irrelevant at the end of the day. Enjoy your new purchases
