Design and build of a FDM 3d printed Roskopf watch

I am designing, printing and building a replica of a Roskopf watch with a budget FDM 3D printer
Can I make it work and how small can I make it work?
This is my first running prototype, the escapement is 5 time time the size of the original watch, the watch itself is 3 time the size
Links to books about the history of the original, including a detailed biography of G.F. Roskopf and a thorough study of his watch calibres
In French:
In English and with additional graphics:

The hairspring rubbing on the balance wheel was one of my major issues with my tourbillon design. That and my inefficient pallet geometry.
