Quartz movements going forward

[sergiu23]

Hello!

I've had some clients telling me that their quartz watch (basic Miyota 2035 or 2315) is going forward 2-3 minutes a day.
As far as I know it's not possible for a quartz movement to go that much forward. Or maybe this can be possible if the watch is placed near some magnetic source?
If you have any info on the conditions under which a quartz movement can go forward more than 1-2 sec/24h it would be greatly appreciated.
Thank you

It's possible, and indicative of an uncorrectable failure of the device in itself. When I say uncorrectable I mean not worth the repair since it usually involves the main processing/circut unit and the quartz crystal. It's routine to just replace the entire movement.

Sorry, I missed your last line. I am not able to list any direct conditions. Most usually involve a fault in the circut which can foul up the accuracy of the movement. These faults can be caused by a plethora of causes. Such as a faulty battery, damage as a result of a battery change, low quality battery, moisture, or just a cheap movement.

In my experience a quartz watch is either working or not working. The only time I’ve known them to do silly things is when the battery is nearly flat but changing the battery in the vague hope it will solve the watch’s ills is hardly scientific.

I've had that problem before. It was the circuit and it was easily fixed.

How was it easily fixed?

I'm not sure what they actually did. This wasn't my watch, it was a preowned I had bought for my wife. It was adding around 2 mins a day. I'd bought it from a B&M and it was still under warranty. Knowing it couldn't be the battery, I dropped it off at the store and 2 days later, they'd fixed it. They said it was the circuit and that they had to replace a few parts, but I didn't really get into any more details. It has been working perfectly since.

Most jewlers just change out the movement these days. I never realized how reasonable some of the higher end movements are.

Thank you all for the info. It really helps.

Probably the flux capacitor!
