This is a Waltham 17 jewel Swiss made pendant watch in working condition. It is a vintage winding type and it is 1 and ¼ inches in diameter. As I have not opened the case, I do not know what the case is made of, so I am assuming it is gold plated or possibly gold filled.Some dark area on the edges are shadows or reflections from outside areas and not dark spots on the gold. It is a pretty design almost art deco in pattern. I believe it may run a little fast. The 24 inch gold tone chain is by Monet, and if available, would add 4 dollars to the price of the 18 dollar price of the watch. I am also listing a smoky quartz heart pendant today and whoever buys that and wants the chain also has the option to get the chain for 4 dollars. My telephone number is 239-431-7089.
