Citizen Elegance Moon Phase Watch

Vintage Citizen Elegance Moon Phase Watch. I believe this watch might be gold-plated? The base metal listed on the back is labeled YP, but I’m not sure if that means it’s gold tone or actual gold-plated. Unfortunately I’m not very knowledgeable with watches. I’m also not sure if this watch is fully functional. The hands do seem to move when you turn the knob but I’m not sure if it’s winding properly so I will be selling it as is. Please keep this in mind when purchasing. The figure shown are for display only and are NOT included.
