I went into this purchase realizing there might be problems, which is why I'm giving this pocket watch three stars. It worked well for two days and I was thrilled! Since then, it has only worked for about two or three hours at a time. Also, it needs a little shake to get started, even after gently winding it per instructions. Since it won't keep running when it sits on the countertop for hours, I'm wondering if it needs frequent movement to keep it going, even though it's not supposed to be the kind of watch that winds itself as you wear it. It is a beautiful item, though, and would probably make a great conversation starter whether it works or not.
