gold? Betty Ross Ladies Pocket Watch

I so greatly appreciat any help I can get to learn about this piece. It's in very good condition but the clock does not run. I may bring it to be repaired. It's gold in color and does not taste like anything which is why I thought it could be gold, or gold plated. It's engraved with roses. The inside says Betsy Ross and there's a serial number engraved inside which reads 7523606. It's on a very long chain with sort of a cinch thing on the chain. I don't know how that works or how it's supposed to be worn. 

I'd really love to know ANYTHING about this. I love knowing the history of my treasures. I'm very interested in approximate date, materials and value. 

I'd most graciously appreciate anyone chiming in with any info you may have!! Thank you!kn
