But if you gave me the choice between the first Dato and the Patek, I would have said Dato.
I don't like the new Dato... Which lost a lor of its character and charm / strenght, IMO.
The Dato is already an icon, and the manual movement is much more pleasant to see than the automatic housed in the 5960.
Now, I find two reasons to love the Patek:
1/ It was the first in house automatic movement ( or was is the one of the Nautilus? ), which is an historical argument.
2/ THe monocounter is really something: Original, and really appealing to see.
I would rather go for the ruthenium, which is to die for,but the blue is traditional for a platinum Patek case.
So, to sum my opinion, the first Dato is the one to get, but this is not a reason to not like and appreciate the 5960P.
I would dare saying that if the Dato is already an iconic Chrono, the Patek 5960 may become an icon...
A watch which is in my list...
Best,
Nicolas.
