Thank you for the reply! I had considered he might have been doing the same, too. These guys are working on high dollar watches, so they don't really care about my POS.
That said, I did some more digging and found more info about the watch.
It's a 1915-1916 marked Dennison case with a BTCo military/military-like movement in it. This EXCELLENT site had the exact case http://www.vintagewatchstraps.com/blogdennison.php
back and the movement description page http://www.vintagewatchstraps.com/movements.php
of the piece I have.

Anyway, I guess my next question is what parts can be used/what should I ask repair places if they have to be able to do it?
Lastly, I have done some minor work on watches, I do have a pretty decent compliment of tools, and I have a mechanical aptitude. Would it be overly complicated to replace the balance wheel myself? If not, any idea where I might be able to locate the part?
Sorry for the million questions. Thank you very much for your help and time.
