For me, these both complications have nothing to do with such a modern timepiece. Or, as I wrote previously, I'm ok with that if it's in a very modern context such as the UN Freak with new materials...
About this last point, do you know if the Tourbillon and Carrousel are exactly the same than the ones we can find in Le Brassus model apart from the fact that they have had a different surface treatment?
It seems not which would already be a good point for me if they have been specifically made for this model.
Nevertheless, a platinum case (I don't understand why to be honest with you) and these both complications don't work with this model for me. May be I'm wrong and too conservative but Tourbillon and Carrousel (especially both together) have to be made for classy and elegant timepieces and not very modern style one (I have the same feeling for a classic AP RO with a Tourbillon or a GP Laureato).
My two cents
