Zenith pocket alarm (Ghandi watch)-help?

[deloid]

I have a couple of Zenith alarm Pocket watches (single winding stem for two barrels). I had to take one apart as I am sending it out for a new balance staff. While shaking out the gears I could see how the tandem wind worked and I could see how the timing would work to release the striker. I still don't have an understanding of the whole watch. I am hoping that there has been an article that discusses restoration or at minimum a diagram of the parts with a discussion about their respective roles.

While I have an extensive library I don't have anything on these watches beyond the history.

Any help would be appreciated.

Of course Angelus then Longines & Lemania also made this (or extremely similar) movements. Any one of these would help.
Thanks-

Someone here must know something about these alarm pocket watches. Anyone have an idea who had the original patent so I can search the patent data?
Please help me as you can...spreading this request to someone who doesn't use this forum would be so helpful. I would do the same for others.

Try posting to the books forum, there may be someone that has dealt with a book that discusses it.
