German Mechanical Clock Hands
These mechanical clock hands are for German mechanical clocks that are post WW2 and includes most mechanical clocks after 1950. Post war clocks are made in either Korea, China, or Germany. Of course, the Korean and China clocks are pretty easy to identify as they usually say 31 day on it. If this is the situation and the clock says 31 day, these hands will not fit.
If you would like to be certain the clock is from Germany, look at the back plate of the clock movement itself. There will always be a stamp with an engraving that says Made in Germany. These mechanical clock hands will fit 90% of these clocks. Although there are some exceptions. Some tubular bell units and some of the older German units are a couple of examples. To be absolutely 100% sure these hands are correct, measure the width of the mounting post on the movement and match it up with the sizes they specify.
