Hi Nicolas Just like to share my 2c about your questions.
1/ Yes the watch is definitely wearable Of course,not for everyone but it isnt that big or 'overdone'. AP did a huge Offshore, Lange did a huge 31, JLC did a huge Reverso and BR did a Grand Minuteur Shape of the watch is perfectly fine in my most humble opinion
2/ Design is very personal, cannot comment much but i think whether it is original or not, it still looks good to the public, by large Just like the Reverso GT series, some like it and some say its too small. Few of us thought it is greatest of all!
3/ The Tourbillon is definitely not in-house but it doesnt matter to me, i couldnt care less of who makes what for who as there is too many complications in the dealings of the industry, AP house JLC movment, VC house JLC movement, Renaud Papi did Richard Mille and etc etc etc etc! Horological brand image? Well i guess everyone could have a first step Who knows if one day Rolex start Tourbillon and Minute Repeaters? I am looking forward to it in fact Datejust is just to 'just'
4/ Product of marketing...i really do not know. I never did go in that deep in thinking of why and whether some watches are made for? One thing i am pretty sure is there wont be many of the Minuteur Tourbillon...just like it's predecessor BR01 Tourbillon. Too many demands but i can see the demands are hardly fulfill. Just like the Gyro or AP Cabinet pieces i guess, sad at some point but thats life.
Well, just my very humble opinion, Nicolas Its good to see people sharing thoughts and feelings
Cheers.
