Orologio da donna vintage primi Rolex Tudor Oyster 17 rubini Swiss Made

Vintage Early Rolex Tudor Oyster 17 Rubies Swiss Made Ladies Watch. The seconds hand does move sometimes, but stops, so I'm not sure how to get it to keep going. The crown also does not screw on. I'm not sure if it was replaced at one point, but it seems slightly larger and won't catch on the threads.
