Guys,

I've got a wheel in the setting which has some rust- watch obviously saw water by the dial stains. There is only this one gear- side facing the plate which has rust. I was wondering if sanding, navel jelly or ? would be best.
I know machinist do some sort of rust removal by electrolysis.
This is a tiny 20/0 Elgin durapower, 17 j movement #702. It's a $1 watch.. but I'd like to get it running nicely again. IF someone can post a parts blow-up of this series it would be appreciated.
