Just grasshopper here. Concerning oiling watches. A while ago I mentioned that I was using mineral oil
to lube these old pocketwatch movements. I read here, somewhere, that it oxidizes and goes rancid.
Point taken. Don’t know about the long time stability of mineral oil but It’s not a permanent fix.
It got my new ebay Riverside to work temporarily so I could evaluate running issues before cleaning.
But it’s viscous ! Heating up the movement with a hair dryer made a big difference in balance swing !
So.. bought watch oil (ebay). Getting to realize that proper procedures, time-tested, can’t be fiddled with.
6539938 16 size Riverside is happily ticking after so many years of neglect and abuse !
1893 ! How something SO fragile could survive for that long is one of the things why I delve into this hobby.
The more you learn, the more you realize how little you know !
