I still think that the PP 5070 shouldn't be compared to the Lange 1815 Chrono, as the movements are not the same ( dedicated for the Lange / adapted for the PP, Flyback for the Lange, not for the PP ).
Same for the 5070 / Duometre ( Foudroyante, in this case ).
As for the level of the finish of the movement, when I see both of them, side by side, I prefer the JLC, as some prefer the PP, or the Dato.
It is a matter of taste, and maybe also, of finish.
As for the comparison post about the Duometre and the Amvox II, I think I already made something like this, it was a quick post.
Best, my friend.
