I have installed gen coronets on mine, centering them slightly better. But it is a very delicate operation - you have to be careful not to get/smear cement beyond the backside of the coronet when placing it onto the dial face. Also, because you cannot really fill the holes without drawing attention to the area, you can only move the coronet up a bit. From normal viewing distances, no one can tell, but, in the hands of an expert with a loupe, it may still be a giveaway.
