I have a Seiko Diver that is running VERY fast. I have not had time to nail down exactly how fast it is but it appears to be running over 1 hour fast in a 10 hour period.

I didn’t pay a lot so I’m not the least bit scared of opening it up and trying to fix it if there is any reasonable chance I can fix it myself. It probably isn’t worth paying a professional as it’s an inexpensive watch.

It's probably been magnetized. The balance spring is sticking to itself and causing an amplitude error.

Have someone demagnetize it, or buy a cheap demagnetizer and do it yourself.

I had two movements in my Tutima UTC do the same thing... both movements had to be replaced. (Tutima did so at their expense, it is a mass-produced Swiss calibre they use in that watch.)

I can't recall the stated diagnosis. It might be that Tutima found it cheaper to do a heart transplant on my watch rather than invest the labor in fixing the issue.

You've driving the DeLorean, haven't you?

A switch to decaf may be needed.

It’s not that. It’s one of Seiko’s smaller divers that has a tiny movement that is known to be hard to fully charge unless you are quite active. Worried that could be the issue I shook the absolute hell out of the watch yesterday.

Hold me closer tiny diver.

Put it in a bowl of rice and pop it in the microwave for 30 seconds on high during the super blood wolf moon eclipse January 20th. Or something like that.

This is exactly what I did with a watch several years ago and worked perfectly. I was flying a lot at the time and one theory is that affects it. Whatever the cause, the demag may work.

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

Magnetization is one possibility, and an easy one to test. It could be other things, too.

About six months ago I was doing quite a bit of soldering. The next few days I noticed my Seiko diver had started gaining about +10 a day. This watch was a consistamt -10 to -15 a day normally. I found an app by Lepsi for my iPad that checked for magnitisn. According to it my watch was magnitized. I bought a cheap demagnetizer off of amazon, ran my watch over it, and the app no longer showed magnitism. And it went back to its normal loss per day.

OK, here's your answer.
Get the Lepsi app for detecting magnetism. Very easy to set up and use and FREE.

I'm IOS so I got it from the Apple App store

Get a cheap demagnetizer from Amazon or eBay. Follow the instructions.

Here's the page. Look closely, they are all the same device. Pick one. Easy to use, I demag my Sinn once a month because computer use magnetizes it.

Works like a charm.

The tiny Asians will not give it back because it is in their rice bowl.

We go to lunch now.

ChuckWall, thanks man! That app is REALLY neat. So my tiny diver is in fact magnetized.

I guess I’m into automatic watches enough to buy a cheap demagnetizer. I retired my G-shock and wear an automatic watch pretty much exclusively now.

Can even a small amount of magnetism mess things up? I’m not getting a very strong reading from my watch but I am picking up magnetism.

This is exactly what I did and it worked perfectly with my Sinns and Breitling.

Ok this is interesting. Another Seiko Automatic of mine that is running a little fast is also reading magnetized. The reading is however much lower than the Seiko Diver

Is it a good idea to periodically demagnetize a watch?

I wondered this so I searched the internet and found someone claiming to get two of their watches to run much more accurately (slightly less fast) after being demagnetized.

Yep. Magnets are everywhere today. iPad, iPhone, you name it. If it makes noise, it probably has a magnet.

Good luck,
