What can you do to make the tourbillon even more precious? How about you skeletonize it until it is completely hidden in the bezel? This amazing one-off piece was made by Thomas Prescher and that little wheel in the middle there is the tourbillon mounted balance wheel. It is wound by the spinning of that flat plate on the bottom and the dials display the date. The time appears on the cylinders on the top and the ball is a three dimensional moon-phase register.

Seriously. Don’t even ask how much this costs. It’s probably not for sale and it would probably explode on your first trip to Costco. This is truly an art watch.
