Is the oring on the stem like an skx? If so you can safely wear it around without fear of water ingress. While you are enjoying it you can be on he lookout for a doner watch. Even if its not running you can buy it for the case and crown/tube?
Edit...
Had a quick glance on the interwebs thiese watches are very expensive indeed!
