Sorry to hear this Michael...
By what you describe it sounds like it could be an escapement issue? An easy fix, hopefully.
On a side note, and sadly so, the only time I have handled an 1858 like yours, was a few months back in a MB exhibit where the watch suffered the same issues as yours. It would´t work.
Here´s hoping yours will be corrected quickly.
Cheers,
Alex
