Wake up American circa 1880

Wake up American Ansonia numbered manufactured for the French export by the 1880s. True piece of collection. At the bottom of the alarm is written "manufactured by the Ansonia clock co. New York. United States of America" The alarm clock goes back using a key that hangs on the back. I managed to make the wake-up call, however I have not managed to make it work. Weight 700g Height 17.5 cm Width 12cm Depth 6.5 cm Waking up is in its own juice, the traces of time are visible, both on the Dial as on metal parts; nothing surprising in view of his age!
