The Datograph!!!
But that was a very biased opinion...
Both are amazing chronographs...
I would say for me, the Montblanc Villeret has a better aesthetic, maybe a more contemporary size, while the datograph is a little uneasy and not for everyone.. Like the first time I tried it, I didn't like how it looks on my wrist
But I think datograph won it in term of movement design.. An originally developed in-house manual wind chronograph, with such beautiful architecture
I would love to see your Montblanc Villeret one day Robin
Such a nice comparsion, of probably, 2 of the world's best chronograph
Best,
Sam
