This mechanical watch is equipped with a balance wheel that beats at 28’800 vibrations per hour. The balance wheel rotates in two directions on its axes in a large ruby jewel, and this kinetic energy is used to wind a watch. The rotation of the balance wheel is regulated by the hairspring, which continuously coils and uncoils, as shown through the Heart Beat aperture.
