Default Re: Avo 8 movement

(Might be) a tiny flake or spike of ferrous metal that gets knocked around when the movement responds, but never manages to get entirely free of the magnetic field. Quite difficult to see, especially if they're 'end on' to a jeweller's loupe. Blu Tack is sticky enough to grab them with a bit of care, especially if you have massaged it beforehand to increase the tackiness. Most troublesome artefacts can be seen with a x10 loupe if the light is good enough.
