Wait some more, there are extra delays with all shipments these last couple of months, so don't worry. Remember, Christmas is around the corner, which adds a serious heavy load to the system.
If you don't even know what the regulating bars are called, you should not really be anywhere near them my friend.
As Freddy states, could be a number of things now. Did you move the correct regulator, or both?
As mentioned in email mate, for the asking price, its too cheap, but as you say could be the poor condition. The rear of the pearl looks suspect, maybe its a replacement that has been glued in after the original being lost? The pearl on a gen insert snaps into place, no gluing needed. Just like the insert itself, snaps into the bezel ring, no gluing needed either.
As mentioned, don't try and insert a new stem if there is still a small broken part of the old stem in there. Make sure this broken part is removed before even trying to fit a new stem.
Detal drill just showed up on eGay, maybe worth keeping an eye on..

Looks like the stem has broken off inside the movement looking at the thread on whats left of it. If you can't extract the broken part out of the movement, by facing the tube down, and gent ally tapping the watch case, you are going to need to strip the keyless down to get the broken part out my friend.
