This is a clock that has kept time for 100 years. There is a hallmark on the back plate. The stones are paste. They were used as a substitute for diamonds. It weighs 21.9 grams. It worked when the crown was turned. The frame is milgrain around the stones, and the watch body is engraved with depictions of grass and flowers. It is an Art Deco style watch. The Art Deco period was from 1910 to 1930, and this item is estimated to be from around 1910. It is almost a miracle that it works without any problems. Thank you for viewing.
