Vintage Gorham Sterling Silver Repoussé Wind Up Alarm Clock

Beautiful Antique Gorham Sterling Silver Art Nouveau Repousse Alarm Clock, circa 1915. The clock is a 321C Case Swiss CYMA AMIC 11 Jewel Wind Up Alarm Clock. I don't know how it works, so I can't say it's in working condition. The clock can be removed, and replaced with a photograph. Frame measures approximately 5.25" x 3.75". It's covered with scallops, scrolls and flowers. Hinged support arm on back. In excellent condition. Needs to be polished.
