Tomy Kongman Game Vintage with Box - Not Working - Spares or Repairs PLEASE READ

Missing the little ball bearing, works, but the timer doesn't count down and move on its own so just keeps it turned on until you move it to the stop point, so there might be something wrong inside

Battery connections are clean and seems to be complete apart from missing the ball bearing
