Elgin Pocket Watch - movement

Thanks, Kerry. I'll see if I can find the movement serial number. Yes, the basil does unscrew. It's still ticking. OMG, that's so C00L. I'm able to set it. So I was NEVER supposed to pull out the top of the crown in the first place. Thanks again. I'll see if I can get the number. No 2405823. There's something on the inside of the cover too. It says KEYSTONE WATCHCASE and below are the numbers 9277426. W0W!
