Handle both, pictures can only give you a limited impression. I've handled both, and I've always thought the Datograph which has a great movement is nice, but it is cold and soul-less. As for B's point...its simply opinion.
Well my vote is very biased - but the 5070 p smokes the Dato in terms of sheer beauty and design though - Lange movements are nice to look at...
But it's like comparing a Ferrari and a Lamborghini I guess
Also a Dato loses value while 5070s appreciate - that's noone faults exc ours (the consumer) but it is wht it is
And of course I had a choice - and I picked the 5070
You definitely made the right choice!
