NWT Disney The Little Mermaid Pocket Watch Necklace

This pocket watch necklace was sold at Hot Topic. The silver tone and mint enamel Ariel silhouette and seashells surround a watch face graphic of Triton’s Palace from Disney’s The Little Mermaid. I bought this quite sometime ago for a cosplay I wanted to do, but never did. Not sure if the battery works because of how long ago I bought it, but the tab you pull out to start the battery is still in it. So it might work. Otherwise, maybe a new battery. Alloy 1 1/2” across
