My vote goes to 270 this time!
I like the simple layout of 233 and dislike the pm/am indicator on 270
But 270 has the auto-wounded movement,it's very convenient to users.
I spent a lot of time winding manually my PAM268 everytime.
...so if I have other option to go, I'll take 270.
at least I can own two Panerai in-house movement.
