I bought a 34 mm Gruen Precision N510 for a few dollars. It was in bad shape. I gave it a COA, polished the case, and have ended up finding it oddly appealing on the wrist.
But the dial is in bad, bad shape.
Missing text, flaking paint, exposed base metal, splotchy tarnishing---this is less "attractive vintage patina" and more "gross."
So, should I redial it or keep it as is? It's sort of borderline for me, and whenever you need opinions, you can always count on the Internet.
