What would cause an automatic watch to run VERY fast?

I check my watches regularly with a small compass.
I might have to put the app on my phone and try it.
I don't own a demagnetizer however I have been thinking buying one.

I found it on eBay for like $9 with free shipping. I’m wondering if it might have other issues as it runs pretty darn fast. It’ll be fun to try to get it running better.

Hmmm. I've worn automatics for 25 years now and never had one become magnetized. I must not have the right personality for it.

Kidding aside, I'd be asking myself what I was doing to cause this to happen.

I bought this exact model for twice this price in 2011.

Going through the earth's magnetic field does it. Navy ships and submarines regularly get demagnetized otherwise they get detected more easily.

We needed to stop asking about the meaning of life, and instead to think of ourselves as those who were being questioned by life – daily and hourly. Our answer must consist not in talk and meditation, but in right action and in right conduct. Life ultimately means taking the responsibility to find the right answer to its problems and to fulfill the tasks which it constantly sets for each individual."

Trapper189, have you ever checked them? It’s weird, I have two watches I thought were a little fast but fine that both read slightly magnetized. I am wondering how that happened. The app on my phone seems to be working well enough at detecting magnetism, I checked it using a few different magnets.

Your phone has magnets in it. Absolutely keep your watch away from anything with a speaker/coil in it.

Mars_Attacks, dude you were right!

I bought a demagnetizer on eBay, watched a YouTube video on the process and that was in fact the issue. My tiny diver is now keeping great time and will be getting a lot of use. Thanks!!!!

I’m glad I bought this demagnetizer. My son has an Invicta 300m diver that was running consistently around one to two minutes fast in 24 hours. Out of curiosity I checked it and did detect magnetism. After demagnetizing yesterday his watch appears to be running considerably less fast. I haven’t had a chance to really look at its performance too closely yet but it appears to be more accurate.

Thanks everyone for the input!
