Hello
These are quite common and an Elgin example will not have the pull of the bigger named examples such as JLC.
It’s a nice watch but pocket watches in general are not exactly popular at the moment so value £100-200!
I would have though any museum that wants one has one so if donated it will sit in their stores
I would get it running and have it as a desk clock - it’s what I have done with my JLC GSTP.
I hope this helps
John
