Hey Fx,
It is nice to have such a comprehensive post with your thoughts on such a rare complication and beautiful watch.
I haven't had the chance to hold one yet but the finishing should be really above what we are used to seeing.
Even if I see those overlaping registers and scales or hands, I don't think I have a problem with it. I think a watch is not to be considered part after part but as a whole.
Thanks a lot for the report and thanks for the video too 
Cheers, Mark
