I know absolutely nothing about pocket watches, I found this one a while ago and sadly its non-functional. As I know nothing please bear with my potentially primitive description of whats wrong! I have taken some pictures of the mechanism which will hopefully help.
When I turn the dial at the top anti-clockwise, it clicks and nothing appears to happen, when I turn the dial clockwise the 2 silver cogs, turn but thats it. The gold "spindle" underneath the decorated plate where the lever sits, which appears to be weighted, sometimes moves. Thats about it really. I apologise for my pathetic grasp of the workings of a pocket watch!
