I might consider selling it. But do you think it is necessary to restore it? Wouldn't a buyer prefer having it in original state, so he has the choice how it will be
restored. I don't know if there are any good watchmakers in my area (Flanders, Belgium).
(I received a certina ds from my grandfather. I've it to a watchmaker nearby, and it came back with big scratches on the case and it wasn't even running right.... Afterwards I tried an other watchmaker, and it still wasn't properly done...)
