The setting lever is loose, or possibly damaged. If you tighten the screw below the stem when seen from the back, it should correct the problem. If not, you'll have to take it to a reputable watchmaker. It would be a shame for the stem to fall out and be lost. As Geoff has already mentioned, it is a good idea to have the watch professionally overhauled. A dirty or dry watch will damage itself through running.
It is an interesting Dial, not one I've seen before. I'd agree with Ambassador C.
