A fresh breakage I would quickly silver solder or have it laser welded. Both no more possible with soft solder on the parts.

My guess, a depthing tool. Insert whatever into the end, adjust and lock off. Check the depth of the other piece against it. Length, not depth comparison tool. -

Happy Sunday people. This one has me stumped. The threaded piece has a dimple in the end. -
I did the math meanwhile: @Jon, I have to apologize for my harsh response! Yes, your math does not correctly convert time to angle of a part of a swing. But funny enough neglected facts compensate each other here and the result is in the ballpark, sufficient precise to work with (in this limited range around middle position). @Zendoc I have no reliable and easy method in which direction to turn the collet. If a coarse error, I observe the impulse jewel as described and turn the collet the same direction the jewel is off the center. With small errors I am wrong every 2nd case ☹️. The dot on the balance rim is reliable only with untouched units, but who knows? Changed staff or removed/mounted roller makes this dot worthless. Frank

I would clean it up. Cut a little slot where it goes into the piece that has the square and solder a small brass plate to to hold the two parts together. Yes you are right it is a German Strike and it has inside count wheel strike, should be 8 day duration. People break hand off because they move the hand by the tips or ends always move from the center.
