I am looking to service a JLC 631 movement watch and am looking for a competent independent watchmaker who is willing to work on it. They're rather unique movements and not everybody is willing. I'd rather not give it a factory service ($$$) - but that might be a last resort. .
You can y Paul at electric watches UK, I don't know enough about movements to know if this is a tuning fork movement or not.
