The 8 Jours caliber is a unique hand-wound movement featuring Eberhard & Co.'s patented winding device consisting of two overlapping mainsprings, which together exceed one and a half meters in length. This innovative system allows the watch to maintain its power reserve for 8 days (192 hours). The dial features a patented power reserve indicator that displays the remaining running time. A porthole on the caseback reveals the decoration of the skeletonized grand barrel bridge. Powers the 8 Jours Grande Taille collection.
