I am completely ignorant about watches. I have been given a Vacheron et Constantin Geneve ladies fob watch. It is 18ct gold with a plain white dial face, Vacheron et Constantin Geneve printed on it. Inside the number 64339 with a signature of what looks like J.Cands, Detached Lever, thirteen jewels.
On the back is what looks like a design of Lillies of the Valley.
Please can you help me find out more about this watch.
