It's primarily speculation, which is why I said "No way to say how many watches are on which planes (if any)..." but there has been a daily cycle of about six UPS planes per day making the trip from Shenzhen to Anchorage and then to Louisville, KY and a round of watch charges in the hours following.
It could be a correlation, it could be coincidence. It's a way to pass the time while I wait.
Did they pass thru on their way to Kentucky? Can someone check?
