Necessary placement position of Seiko Kinetic Capacitor


This is one of several photographs taken with Macro detail to help anyone wanting to install a capacitor in a Seiko Kinetic watch.

When I first started there was very little guidance, save for some hasty videos that assumed too much prior knowledge, or photos that made little sense.

So, with the basics:
1) The all important peg.
The Mylar Insulator has a hole which slips over this peg...
doing that initially and correctly will save you frustration galore.
I will post another photo later about the orientation of the Mylar Insulator, as it absolutely must be, so that it does cover what it needs to cover, and yet does not block transmission of a charge where it shouldn't.
A tricky little piece of dexterity that caused some cursing occasionally.

2) A specific little square notch that is only for the Left Hand contact of the Capacitor.
If you start with the Capacitor "upside down" (with the shiny side face down" unlike other watch batteries, and slide it tipped downwards initially, as shown in the photo, then it will slip under the little lip that is has to hide under, which is at 12 o'clock in the photo

3) This is a little detail most videos never mention: There is a tiny foot
on the end of the Right Contact.
That foot absolutely must be in contact with the tiny piece of materiel as shown in the photo.
If it is not, the capacitor won't work.

4) A piece that touches one of the coils, as it is supposed to.

Caveats: 1) Do not use metal tweezers
2) Do not Short the Bridge Plate and the foot's resting materiel area
3) There is a gold toned metal spring retainer...be certain the Capacitor is fully inside that spring, and not merely laying on top of it.

(I like to envision the foot as the bottom of the number "9", and in that manner
the gold toned spring is at the top of the "9")

Warning about Seiko Kinetic batteries and capacitors


I frequently am sent Seiko Kinetics and the User says "this watch stopped and I tried to put a capacitor in it but it still didn't work. I know the capacitor was good because it was new and I checked it with a battery checker."
A Seiko Capacitor (battery) must NEVER be checked with a battery charge measuring device of any kind. The inexpensive battery checkers that are sold on eBay or Amazon will deplete a capacitor immediately and fully. And when the "new" capacitor is placed into the watch the watch will not run. It cannot run because it has not power to run because it has a depleted capacitor. And that capacitor will NOT recharge. The battery/capacitor is DOA. Dead. DNR.
##### (Another frequent mistake is to use metal tweezers when installing the capacitor instead of plastic tweezers. Or making contact with either the + pole or the negative pole. Or not correctly installing the mylar insulator in EXACTLY the same position it was when the battery was removed. It is tricky, and it trips up a lot of battery replacement attempts.
And occasionally I receive a watch that the User installed the battery upside down. A Seiko capacitor does not go into the battery well like most watches; it goes in "upside down", with the Positive side DOWN, and the negative side facing you when it is in the well.
But the most common reason a new capacitor placement does not make the Seiko Kinetic run is that when the rotor assembly was removed the User pressed down, even the slightest bit, when removing the screw that holds the rotor. That downward pressure pushes the second hand into the watch crystal, and it is now simply a dead watch.
The slot in the Rotor screw is the thinnest slot I have ever encountered, and I have several expensive screwdrivers that are truly precision.
But I have to use a whetstone to carefully grind down a precision screwdriver to an razor thin tip, before I can safely remove that Rotor screw.
I often break a single edge razor in half, and just use the razor blade, because
it is thin enough enter into the slot of the screw.

Unfortunately, the Seiko website does not have a serial number lookup, so you'll have to identify the model. The "8123-7190" is what Seiko calls the "caliber code." Entering that on the page linked below will narrow down the model number list for you. Clicking on the link for your model will give you the instructions in PDF format. The instructions for your model tell you what size battery to use. For example, the manual for the 8F32 states on page 11 that the battery size for that model is CR2412. (Note - be sure to get the correct instructions; different models have different battery sizes.) "Automatic" Divers watches have no battery, they are powered by a spring mechanism.

SADLY WE DO NOT KNOW . NO WATCH MAKERS HERE GIVING OUT FREE INFORMATION

the make of the battery is of no importance
it is the size and voltage that counts
if the watch is water proof , you will need to have a jeweller or watch maker replace the battery as the case will be sealed

Vital danger to be aware of when working on a Seiko Kinetic.


When replacing the capacitor/battery of a Seiko Kinetic watch it is necessary to remove the pendulum that swings to create the electricity to charge the rechargeable capacitor.
The pendulum is fixed by a screw with a very thin slot.
If that screw is pressed down while it is being removed it will push the hands of the watch into the crystal, and the watch will be ruined.
It is vital to only turn the screw, and not apply pressure downward.
The slot of the screw too thin for most screwdrivers, and I either use a knife sharpening stone to shave off the sides of a precision screwdriver ( I like Wera brand screwdrivers ) or I use a razor blade.

How to charge a Seiko Kinetic with an electric toothbrush charger


This is the Sonicare "Advance" model charger.
Other chargers will work, but many do not open with screws, they instead are welded or glued shut and must be shattered to get open.
I use the Advance charger for my toothbrush and to charge my watches.
This model has 2 very simple screws.
And the inside is arranged such that a watch fits logically over the flux.
Photo 2 shows the bottom of the charger.
Photo 3 shows the same charger with the screws removed and the bottom plate removed.
In every model of charger there should be a rectangular section and a circular section.
The circular section holds the electromagnetic flux generator. That is what will generate the power to charge your watch.
In most Seiko Kinetics the Generating Coils lays beneath the 8 o'clock marker on the watch.
You would like to have that 8 o'clock marker pointed toward the 9 o'clock spot on the Circle.
(See Photo 5)
On other chargers and with other watches simply rotate the watch around stopping ever 10 degrees or so for 10-15 seconds, until the watch starts to tick in 2 or 1 second intervals.
It may take several days to charge your Kinetic if it was fully discharged.
I hope this is helpful

Removing case back screw type


When I started replacing the Capacitors (rechargeable batteries) in Seiko Kinetic watches 10 years ago the most difficult part for me was getting the darn case back off the watch.
I struggled and cursed and busted my knuckles and strained a thumb and lost those tiny tiny (and expensive) screws in the carpet and so on.
So I want to save others the same frustrations.
I have 2 ways now that I use to remove the screw-back case backs from Seiko Kinetics.
This is one method.
I will document the other method in a later post.
You will need:
A Nut appropriate for the size of your Seiko's case back
Krazy Glue or something similar
Acetone
A wrench or some kind

1. You will clean the case back to remove oils and such that inhibit the Krazy Glue from making a firm seal
2. Glue the nut onto the case back
3. Let the glue set. I use baking soda to expedite that process.
4. Don't get impatient.
5. When the Krazy Glue has set just turn the nut with a wrench and
the case back will easily turn off.
6. Then simply soak the case back with the nut glued onto it in a capful
of acetone
7. The acetone will dissolve the Krazy Glue and the nut will separate from the case back.
8. The case back is now free from the watch, and you have access to the inside of the watch to replace the Capacitor.

Voila.
Finished

There are other methods touted all over the Internet.
Trust me, over the years I tried them all.
The biggest scam I think is the sticky rubber ball they sell.
You are supposed to be able to just buy that rubber ball and press it against the case back and turn it and the case back will come off.
Hogwash.
Dozens of the Kinetics I have worked on are over 20 years old and have never been serviced, but have been worn daily and are simply horrible to work with.
The gaskets ("O-ring") is usually dried out and shrunken and adhesive.
There is grime and dirt and skin oils that have degenerated and more and more.
Don't waste money on a rubber ball.

I will post the other method soon.

Let me know if you have any questions about Seiko Kinetics.

Tip

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.)

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!

Replacing the Battery/Capacitor of a Seiko Kinetic watch


There are some articles and videos circulating recently about replacing a Seiko Kinetic Capacitor with a common Silver Oxide battery, the type used in common watches.
In a word: Don't.

I have replaced over 200 Seiko Kinetic Capacitors (sometimes mistakenly referred to as a "battery") and am very comfortable discussing the right way to get a Kinetic running correctly, versus the wrong way.
Can you remove the Kinetic's rotor and put in a Silver Oxide battery the same size as the previous Capacitor and your watch will work? Possibly.
Will you install the new battery upside-down? Very likely.l
If you touch any of the vital contacts inside the watch with the battery will it fry your watch? Possibly.
Will the watch overheat or burn? Possibly. Typical batteries don't have the inner chemical makeup of a Lithium-Titanium Capacitor.
Is the pendulum that is weighted and designed to turn the rotor going to be negatively affected? Probably.

The cost of a correct Seiko Kinetic Capacitor has dropped dramatically, reputable sources like Amazon now sell genuine Seiko Capacitor kits for about 20 dollars.

Why risk a 400 dollar watch to save 10 dollars on a battery.

Let me know if you have any general questions about Seiko Kinetic Capacitors and/or Batteries.
There is a lot of inaccurate information floating around, which can be expensive.
