Hi Randy,
No offense taken here. Those of us that have been working on time pieces for an extended time, weather clocks or watches are always open for suggestions and new ideas 
. The movement is a 470 and yes the mainspring bridle and barrel outside wall was properly greased. I only worked on but a few self winding watches but never ran into this issue. Your suggestion is well noted and I will wear the watch to see if it will maintain it’s time. But first i must get a band for it. I will keep the forum updated.
Thanks again Randy
Jim
