To my knowledge, this watch was produced in 1924. As already said, you would most likely need a donor movement from another watch, which is either complete, than you would not touch the donor or incomplete, and then it must still have the parts you are missing. I recently shortened the number of watches in my collection (and bougth some new ones, when something was missing in my systemmatic approach). As I want all watches running, I had some restored, but that had to been seen in connection with the collection as a whole. Attributing the cost of repair to the individual watch, there was not a single one where this was worth the expense. Of course, this has to be seen also in view of a sentimental value. I had a wrist watch fixed from my grandfather, which my mother was wearing lateron for many years (mens wrist watches were rather small in these days). I could have bought three similar ones at eBay, in working condition, for what I have paid. It's alwas a difficult thing to decide. In the condition your watch is in, it is presently a piece of precious scrap metal (sorry to be so rude), but simoultaneously the basis to make something of real value out of it (especially because of the alarm-function and the famous makers of that watch), and the price decides what to do, which is a different thing for anyone. I had a watch with many missing parts, irrepairable, made around 1650 - 1680 by a famous watchmaker. This is something I could have kept, even as a fragment, but I also gave it away. I am writing this all at length, as it is also one of my major problems concerning my collection, which is quite large and put together over the last 30 to 35 years. Somethimes, it makes more sense to leave it as it is, sometimes...
