If you have a microscope check for any flat spots on the pivots and carefully check the jewels to see if the holes are still cylindrical. Make sure the wheel is true and in poise. Make sure the pivot diameter is the proper diameter for the hole in the jewel and check for the proper length of the pivot between the pilar plate and bridge. Make sure that only the cylindrical portion of the pivot is spinning in the jewel hole and that the conical portion is not rubbing on the jewel. Somebody could have relplaced these parts and pressed the jewel in too far and/or made a new pivot and did not fit it properly for the watch. In short, make sure everything fits the way it is supposed to.
