A warm welcome and glad that Fab convinces you to post ! Now you will ...
NOT be able to strop ! LOL π !
5146 is a great start ! My first Patek is also an AC, 5396 because I loved its functionality along with a well balanced dial with a classic look.
For your second piece, 5170 is a good choice. I would also consider a worldtimer because they are iconic Patek pieces.
Good luck and have fun !
