I think you're asking exactly the right question!
And, in my opinion, Jean Arnault is still caught in a kind of loyalty conflict: he loves watchmaking and would like to make purely horological watches, but doesn't want to betray his brand and group (or something like that).
And my impression is that his desires are only fully realized for the moment in bespoke pieces or in the purely horological brands for which he is responsible: Daniel Roth and Gerald Genta.
Just my personal impressions, but I might be completely wrong.
Best, Emmanuel
