As for the smoothness of the pushe, it is not as smooth as the Dato, but very good although.
As for the case of the Duo metre, it will house several nice complications, as the Chrono is the first member of this family.
Esthetically speaking, we go naturally fiurther than any Master Watch, but yes, there is a certain "air de famille".
As for the macros of the dial, they were taken on the definitive watch, but you don't have to forget that this kind of macros enhances all...
Best, my friend.
