Hello-
I am considering to tackle the repair of my w115's VDO Kienzle clock. It is a mechanical clock which uses 12V to self wind itself. I have also removed one from a parts car and it appears that someone has already fixed it. After a cleaning, I was able to get it to run. But I noticed that the clock from the parts car re-winds itself very frequently. I thought I read elsewhere that they run for a couple of minutes between windings, but this clock winds itself every 47 seconds. If you can hear your clock wind, could you check how frequently your clock re-winds itself? (I have never had a running clock installed, so I don't actually know if it is possible to hear it click). Anyway, if 47 seconds is in the ballpark, I will probably just swap out this parts car clock into my vehicle. Thanks.
