It all depends on your own taste, Luca.
The blue face is a bit sportier, when the grey dial is a tad more chic.
In both cases you won't go wrong.
Now, if I had to choose between a JLC Duometre à Chrono or this PP 5960, I would go for the JLC.
The movement sings louder to me, the complication too.
Ciao,
