Well I thought I'd do a quick bit of googling first and low and behold I found a solution ... one that was simple enough I figured I'd just post the answer to my own question here just in case anyone else here has had this problem.



This watch is one of the watches I got when my dad passed away back in June (the other is my grandfather's early '60s Rolex Oyster Stainless that isn't running at all so I need to eventually take it to a shop). I remember my dad tossing this watch into a drawer back in the '90s complaining that it was running fast but he didn't want to spend the cash to take it to a watchsmith. Too bad all he had to do was smack it (if I had a nickle for every time he smacked a non working appliance or TV ).
I have a SEIKO self-winder/Automatic I bought at the PX in Germany in 1980.
I have worn it daily until just a few weeks ago.
It has started loosing time!
A bit more than 5 minutes a day.
I may still try your "tap" method and see if it can be put right.
Last place that replaced the crystal said they can't repair these, I would have to ship it off to a shop that works on such devices.
I would like to get it back into service, wearing it is just part of the daily routine!
