Everything you say makes sense. But to be honest, this kind of watchmaking is not my cup of tea. It is very challenging to make such uber thin perpetual, but that is all it is doing - making an already thin and elegant watch thinner. To my taste It is an artificial challenge, it doesn't address the power reserve limitations of a perpetual (VC), safe setting of the calendar indicators in both directions (MBF), moving all the indicators simultaneously (Lange).
It looks great, but I would not choose it over the regular model, especially the ceramic version.
