Job Numbers 210149
Here is the broken stem, the sleeve and the crown. On most vintage American watches the "snap" in and out of the crown is a function of the case and these parts in the neck. You can see how the stem pops over a shoulder in the stem. You can also see the larger hub on the stem that pushes the case's latch spring down to open the front.

The second photo shows the stem I found to replace the broken one. It's a very good match (these parts are not standardized).
