I was at a garage sale and asked if they had any watches. They went inside and came out with this, a Lord Elgin, two Armitrons and a Gruen cal 823.
I popped a battery into the Accutron and it didn't run. Then I remembered reading about someone tapping his on his workbench. I gave it a light tap and it's humming away. I guess sometimes the tuning forks need a little push.
