I'm a little confused by your posts. If you are winding the watch counter-clockwise, then you are not winding it at all.
So you are strapping it on and letting your wrist do the winding from scratch. Unless you are extremely active during the day, it's not getting to a full wind and there isn't enough juice in the mainspring to get through the night.
Try winding the crown clockwise for 30 winds, then wear it for the day. If it is still running and keeping correct time by morning, then it's probably OK.
The "61" date code and 19 million serial number probably went together from the beginning and could have very well been sold in 1962.
Hope this helps,
