Hi all,

I have a seiko sumo with a 6r15 that's 10 years old now, so it's in need of a service. However, as its a cheap movement I'm reluctant to do so. I'd rather run it until its death and then replace, if necessary.

The movement is running about 3 minutes slow per day, which is quite significant. The cause of this is likely because the movement needs a service. However, if its due to magnetisation of the movement then I would like to get this resolved as its cheap to do so.

Is there anyway to check if a watch is magnetised? I've searched online and the usual recommendation is a compass (which I do not have) to determine if its magnetised. I also don't have a demagnetiser so I can't just do it myself. Are there any other methods we can use with everyday household items?
