Antique Cartier Desk Clock

This is a 1920's Cartier Desk Clock. Authentic Cartier 8 Days Alarm Clock. It has a solid sterling silver body (S23) that is wrapped in beautiful red leather with Cabochon Jade accents mounted on a Gudda Percha base. This is a truly beautiful time piece that is in remarkably great condition. I accidentally bumped the balance spring and nudged it out of balance and now the clock doesn't work.
