Case looks healthy enough... movement looks a little more 'worn' than usual but not sure if that's a problem. A watchmaker can probably get it to run great. If the watch is from '69 as the caseback indicates, it shouldn't have a Mk4 dial as it appears to have now. Not a dealbreaker in my book, it all depends on the asking price. Overall looks like a nice example. I dig the faded fat font insert and patina on the dial (lume seems to be all there).
