Pocket Watch Names

How a late 1800s, Jaccard Jewelry Co. Pocket watch worth?
I have a Pocketwatch the late 1800s, and the outside is gold (It has not tarnished in over 100 years). It is in beautiful condition. It does not work, unfortunately. Is about two inches in diameter. The back opens to reveal a name engraved, behind which is the mechanical operation. just an estimate, perhaps how much it worth?
You should take it to an antique dealer, especially one that deals specifically with antique jewelry that since most of us here are not experts on topics such not to mention that we are not looking at it
