Lucerne Faceted Acrylic Pendant Watch

Got this vintage Lucerne pendant watch. It's got a cool amber or orange faceted acrylic case that looks like a big gem. It's hanging on a simple ball chain. The dial is gold-toned and says Swiss Made at the bottom. It's a neat little retro piece if you're into that mid-century style. Not sure if it's keeping perfect time but it looks pretty good for its age.
