Good point, and this is worth considering for a family piece with sentimental value. It really depends what type of restoration the OP is interested in. It can be sent to Omega in Switzerland, and they will perform a soup-to-nuts restoration for a cost. This may involve replacement of the dial, or complete repainting of the dial. Other parts may also be replaced with new-but-authentic service parts. They will also get it running well and provide a warranty. The watch will look pristine, but may lose some of its "originality" along the way, if that matters to you.
An independent watchmaker might perform a restoration with a lighter touch, by simply cleaning the existing dial as much as possible, replacing the crown with one that is period-correct, and hunting down any parts that are needed to repair the movement. Most likely, this would be less expensive than a factory restoration, but still probably more than the value of the watch.
So there would be a difference in price and also the final outcome. Some people want their family heirloom to be restored to like-new condition, and others would like to retain more of the watch's history.
