Is magnetisation of old automatic watches really a thing? Son's watch is a bit too fast even though it is recently serviced and regulated.
I can see plenty of ways it could have been close to magnets since. Including headphone speakers and the like. I think it makes a compass needle move a little when held close too.
Are the cheap degaussers at amazon worth a shot? What are better but not too expensive euro sources?
