G'day,
to each his own, just that there´s a technical challenge to keep in mind.
The large date requires a likewise large date wheel, which limits possible positions for the second/power reserve indications:

It´s not a technical drawing and dimensions may be slightly off, but over the thumb it´s not possible to place indications within the red circle.
The alternative would be to move the power reserve mechanism out of the movement and apply a module under the dial, which would make the large date appear "sunken in" and add at least 3-5 mm in height. Not sure such would be a more pleasing sight, though.
Leaving out the large date might do, just that would mean to omit an iconic feature for Lange watches.
So in some way it´s in fact a compromise, which makes itself seen MUCH more in rectangular movements of limited width/height. Still i find the second hand essential (because of the stop seconde mechanism) and the power reserve indication a nice visual counterweight.
To each his own
Cheers,
Peter
