Vintage watch Quartz

Just after opinions.

Having done some research it would appear that Oysterquartz watches are very accurate, so much so that they should hit their markers when going around on their 60 second tick tock sweep.

So would it be that after a restoration this should be the case or is there room for it being a little off from the marker? Or is it expecting too much for a 30 plus year old watch? Or a restoration is just that nothing to do with the movement being adjusted?

Thanks
