Far be it from me to question your opinions on this, but do you really think that this is worth $600?
I guess the case and crown are worth something, but beyond that, it's the proverbial pig in a poke. You'd have to assume the movement is shot or at least would require much work. New pusher. New crystal. Possibly new hands. And a refinished dial?
What would it be worth when it's done? I don't know but quite a bit less than an all original watch.
