Hi guys, I am completely new to watch making and currently I am iterating on my cleaning process to get it right. My current process is a 3 step cleaning routine in an ultrasonic cleaner and drying afterwards in a food dehydrator at 45°C. 10min wash with Elma Red 1:9 at 58°C 5min rinse in distilled water 2min rinse in IPA 99% 10min drying in a food dehydrator at 45°C I have an old ETA 2842 which I use to test the process and the cleaning in general works pretty good...but I found one strange thing during one run I did yesterday. After the 10min wash cycle in Elma Red 1:9, the bright silver balance shock jewel metal housing colored black. Do you have an idea what happened here? Thanks, best regards Michael -

I don't know if its pushing it in too far, but because the available batteries do not have a raised contact, clear of the case? I'm not keen on the idea of soldering to a battery, but possibly stick a small washer or similar metal spacer on with conductive paint or adhesive, plus a nylon washer around it? -
Agree with Tom, a timegrapher shows more than regulation. Such as beat error. Also with a timegrapher you can regulate in different positions to get a better average. -
Welcome Bob, enjoy the forum.

Thank you that was an interesting article. I definitely could have pushed the battery in too hard, thus shorting it out on the case. The 'switch' on the keyless works is another possible candidate as the movement is slightly loose in the case and something on the dial side could be shorting as well. I will probably need to dive in to giving it a service and try and overcome some of the problems as the article author did.
