Gold and not plated the back it solid gold
I found it in a demo house we was tearing down.
Thank you for contacting Mearto with your appraisal inquiry.
It is a lovely gold filled open face pocket watch by Hampden Watch Co, fitted with a full plate movement signed Dueber Watch Co. These pocket watches are often seen at auction, in either specialist auctions or antique sales.
A case that's marked "Warranted 20 Years" meant that the gold-filled case was made with a layer of 10K/14K gold, and was guaranteed that the gold-layer would not wear through to the brass for a period of 20 years.
I believe this pocket watches could achieve within the estimate.
Do let me know if you have any additional questions. Many thanks!
Huge apologies, I didn't include the estimate of £80 - £120. Many thanks.
