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.
