Ulysse Nardin Royal Blue Tourbillon.
A watch I always loved. I am not a big fan of Tourbillons, but along with the Gyrotourbillon from JLC and the Tourbillons with Bridges from Girard Perregaux, this Ulysse Nardin is an exception and a very good one.
41 mm Platinum case, not jeweled, my favorite version of the Royal Blue.
The play of light and transparency is just sublime.

Another dream watch, for me.
