··Omega Qualified WatchmakerMy daily "Goldie" 3861 stops from time to time completely, when I have my stopping function running and the very big seconds hand is close to 12, when the subdial minute counter should start to make the next step ... but it does not. It stops completely by itself. Not every minute, not every time when I use it, but frequently after 5 min or 10min or sometimes
after 3 hours using the function.
Even the balance stops than completely, what I can see from the glas back.
When you say "stopping function" you mean the chronograph, right?
Is the watch fully wound when this happens, and are you winding it daily?
