Recently picked up a nice cushion case electronic for a couple bucks just because I haven't come across one yet. And being a Timex I knew that it most likely wouldn't work but hoped it would. I got the correct battery and put it in, gave the balance wheel a little flick and it started running to my suprise. Unfortunately it only runs face down. When tipped up the balance stops, I assume that it is wobbly and rubbing against something and that is the problem. The movement says 247 I believe. Does anyone know how I would go about fixing this?
