Hello.I have been working on a vintage movement. It is German movement, PUW 1561. It is automatic and has date with quickset function by pulling and pushing back the crown. Before I disassembled it, the quickset did not work instead the date changed as hands passed 00:00.  However, as I am trying to put the watch back, the date won't change either by quickset or just manually.  The date disk won't move no matter how long I move the hands. I think I have assembled the date fun
