Yes, this one needs some love and care. There's been a bit of butchering on the centre wheel pivot jewel/bushing where it appears to have been peened at three points as well as having an incorrect retaining screw fitted. Screws are also missing from the balance pivot jewel and the swan neck regulator. Casing screws are also missing. It's a decent watch so spending a little to bring it back to life would be worth it IMO.
BTW, I think it's a Cal 19''' NN L17P first produced from about 1905.
The case is most likely rolled gold made by the Brooklyn Watch Case Company.
If you Google it there are many other watches like yours.
