This necklace watch is so wearable! The enamelled chain is 23 inches long and the enamelled bars are rectangular. What makes them extra special is that the rectangle edges are not enamelled and there are lines near the ends that are also not enamelled so this adds a nice pattern and makes the links fancier. The ball is 21mm across and has a crown like bale. This is hung on a swivel lobster claw that is hidden by a black enamelled arrow. The clasp is marked Argent ( French for silver) . The watch face is porcelain and the whole is in nice condition with some enamel loss to a few of the bars, but not to detract. The watch is working. C. 1920 and French.
