The Duometre is the only Chronograph where Time and Chronograph are equally important.
So, time and chronogrpah informations are equally important.
You don't have the 2 big second hands moving all the time, as you have to use the chorongraph function for that.
On the other side what do you think about the Date of the Datograph, which is lacking a Zero on the first 9 days?
Is it a technical and aesthetical improvement, too?
I never read someone complaining about the 2 second hands of the Duometre, but I read several negative comments on the Date of the Datograph.
For your information, I never complained about the hands of the Duometre, nor about the Date of the Dato.
And I owned both, for several years.
Best,
Nicolas.
