Seiko Watches - Recent Questions, Troubleshooting & Support

It is unlikely that you can, unless you have the special tools required, especially for watches with screw down backs. Take it to your local jeweler, they have the tools and all the dozens of batteries in Lithium, Nickel Metal Hydride and Silver Oxide flavours. Cost is $8 to $15 and done whilst you wait.

Wow, Seiko is a all-time favorite! Why not take it to a Seiko Repair Center and pay a few bucks to have one professionally installed?

Real shame if YOU installed a knock-off and it leaked on you!

Mistakes made when installing a capacitor (battery) in a Seiko Kinetic

Here are some common errors I see when I repair a Seiko Kinetic watch that
someone has tried to replace the capacitor.

1) Attempting to use a silver oxide "coin battery" or common watch battery.
In a word: Don't.
The silver oxide batteries are not meant to be recharged.
They may leak. They may ignite. They are a bad idea.

2) Putting the capacitor in upside-down.
Although this seems foolish, in fact it is quite common.
The way a common watch battery goes into the typical non-Kinetic watch is
upside-down from how a Kinetic capacitor is placed.
The Seiko Kinetic Capacitor has a + and a - pole, and inverting these can result in a fatal short.
And there are copper contacts that must rest on extremely small contacts precisely.
Putting the capacitor in like is done with a regular watch just does not work.

3) Touching the copper appendages, or touching the watch contacts with metal tweezers.
Use plastic tweezers.
Wear latex gloves.
And I also use a wrist static band that I use for computer repair.

4) "Testing" the battery with a battery tester.
Don't. It severely discharges the capacitor.
You can instead install the battery, the Mylar insulator, and the hold-down, then use 1 screw only to secure the battery in the battery well, and then check
the watch, as it should be running on the new battery.
Use the Indicator button now to check the battery strength.

5) Pressing down on the central screw that holds the pendulum in place.
This can permanently stop a Kinetic watch.
The Pendulum screw pressure goes directly to the hands, and pressing on the screw while removing it to remove the pendulum may push the hands complex into the crystal, and stop the watch permanently.

The slot for a screwdriver in that Pendulum screw is very very thin, and
to avoid having to press hard I simply use a single edge razor blade.

6. Not replacing the gasket ("0-ring") when replacing the capacitor.
Esslinger is a good place for genuine Seiko gaskets.
Don't get cheap gaskets.

7. Not getting the exact Seiko capacitor for the model.
A 5M43 for example takes a 3023-5Z capacitor.
Several web sites will direct you to the right combination.

8. Buying a pre-owned Seiko Kinetic that was advertised as "New battery installed."
I see common coin batteries installed.
I see very old capacitors installed that have not been made for over 10 years.
I see the right capacitor installed but installed upside down.
A brand new Seiko Kinetic that has been sitting in a display case in a jewelry store may have a depleted battery, simply because the capacitors may self-degrade over time.
Jewelers may not have the integrity to put in a correct genuine Seiko capacitor, which may cost 30 dollars or more.

Enjoy your Kinetic. Engineering greatness.

Do not test a Seiko Kinetic Capacitor with a battery tester

The Seiko Kinetic watches use a Capacitor (rechargeable battery) that costs
between 16 and 30 dollars.)

They drain drastically if they are tested using a typical battery tester using 2 prongs to get a reading. It shortens the life of a capacitor significantly.

Don't ruin a good capacitor by testing it with a battery tester.

You already know if it is doing the "2 second Tango" the capacitor is depleted and needs replacement.
A lot of Kinetics sold used will tick when worn and a little while after being taken off the wrist, but then stop.
Those are depleted capacitors, that need to be replaced.

If it is a 10 second Indicator swing replace the capacitor within a few weeks.
A 20 second swing is good for months in most modern Kinetics.

The Kinetic capacitor will not be at full charge when first installed.
Either wear the watch you installed the new capacitor in for a few days,
or put it on an electric toothbrush charger for a few hours, and it will reach maximum charge.

Money saving Tip about Seiko Kinetics

Seiko makes genuine Seiko capacitors for the various Seiko Kinetic watches.
The Seiko capacitor 3023 5MZ is about 16 dollars on Amazon right now, it fits the 5M42 and 5M43 Kinetic.
The Seiko capacitor 3023 44Z is about 26 dollars on Amazon. It is for the 5M62 and 5M63 Kinetic models.
However the less expensive 3023 5MZ replaces the 3023 44Z for 10 dollars less.
And also comes with the 2 accessories I like to replace when I install a new capacitor, the metal hold-down, and the Mylar insulator.
The 3023 44Z, although more expensive, does not include either.

Both capacitors are the TC920S.

Don't waste money buying the 3023 44Z.
Get the 3023 5MZ instead. It is 10 dollars cheaper and the same thing.

(Use plastic tweezers always, and don't touch the contacts, ever.)

The internal cell may require to be changed. It is very important you use the proper cell for your watch. This is assuming the solar cell is working properly.

Take it to a jeweler for a demonstration of how to remove the back without damage.

you can call Seiko and they will sell you a new strap, though fair warning they are not cheap. You can also if you want just any watch band not having to be the exact band , try a watch repair shop and they should be able find one that fits.
