This is a German made Jauch clock from the 1970s, I think. It is time-only spring driven clock. All I did was oil it when I got it.
It runs a full 8-day cycle with no problem. However it gains about 5-7 minutes at the beginning of the cycle and loses the same at the end of the cycle. Is it the nature of the movement or should I look further for other issues?
