Winding mechanism

The extreme miniaturization of the winding mechanism inspired the firm to file a second patent for the three-dimensional multiple meshing teeth, which drastically reduce clutter while optimizing the watch’s operation. A mechanical watch of this complexity would typically involve twice as many turns of the crown to wind; however, the exclusive winding system in the Ottantasei and its patented spherical differential halves this number.
