So check this out I had an elgin 539 a-11 hacking movement with a bad balance, i swapped the balance and realized it just did not work, (and yes i checked the hack lever, the stem was still in) I did nothing to this movement, didnt disassemble clean or do anything. I put the movement back in my organizer bin, and a couple days ago I opened it to start the service on it. However oddly enough as soon as I picked it up it started ticking away, so then I winded it up put a dial and hands on it and boom! This thing is still running! its been almost 42 hrs now and its keeping DEAD accurate time. I have never been able to get these results even when I do service them....like what are the odds, did some kind of angel possess this watch or is this just something that happens???
