I understand your dilemma — I went through the same thing myself. For me, it came down to two things: the size and the metal/dial combination. On your wrist, the 57 definitely looks better. And in terms of aesthetics, the platinum with the blue dial ( the original) and, in my opinion, the nicest version. My own debate was between the rose gold with the black dial and the platinum with the blue dial, but in the end I decided on the platinum/blue since it feels more versatile and will probably become my daily watch.
As for the movement, I’m perfectly fine with the automatic, even though I generally prefer a hand-wound movement.
