SEIKOSeiko Kinetic Capacitor 3023-5MZ

How often does one take a watch apart, put it back together and it works? I replaced these parts in my kinetic Seiko and voila it works like brand new. These types of watches can be sent off for repair but that can be expensive. This is the perfect solution.

I just bought a 1990's era Seiko Kinetic watch a couple of weeks ago, knowing in advance that it wasn't running. It's add copy didn't state there was any damage, but offered it for repair or parts. It appeared to be in beautiful condition, with a perfect dial face, perfect hands, and the matching titanium and gold colored bracelet. The bracelet showed no wear and even included a spare link to enlarge the bracelet if needed. I already have a Seiko automatic (5 series) and a Chinese knock-off, both automatic self-winding movements. What drew my attention to the Kinetic is the fact that this series of self-wind Seiko watches has an oscillating rotor, just like the other automatic mechanical movements, but instead of the rotor winding up a traditional main spring in a barrel, it turns a miniature "rotor and stator", like an alternator in a car. This little charging system charges a capacitor, which in this case looks like a typical watch button cell, but with small power-out and power-in lugs. The charged capacitor provides the electrical current to operate the watch's quartz time-keeping circuit and a stepper motor to move the watch's hands. This system combines the best of both worlds: A physical charging system powered by the movement of your arm/body, feeding a quartz watch circuit that keeps even better time than just about any mechanical watch movement! No batteries used or needed! I do watch repair so installing the replacement capacitor was very easy. But anyone can do this; all that's needed is a steady hand, a tiny regular tipped screwdriver and the capacitor kit. Although there is one thing some Seiko owners might need and not have and that depends of whether the last time the watch's screw-back case cover was removed and replaced, that it wasn't screwed back down so tightly that it can't easily be removed either by hand, a rubber ball case-back remover or careful "persuasion" with a piece of wood and a small mallet or hammer tool. It this is the case, a case-back removal tool will be needed. If you don't have one of these tools you can order one on line when the capacitor is ordered. The price for both is very likely to be less than any jeweler will charge to do this repair. As for the capacitor kit? Well, it was made by Seiko, fit perfectly and is working great!

Thank You for prompt courteous service on this part order, and to say it directly to your business - also send a complement via Amazon with a 5 star rating for you. I just installed these parts myself in my Seiko Kinetic Watch (SM042-L99 Titanium) that is now 12 years old, and still looks like new.The original "Ion Rechargeable Capacitor/Battery #TC920S" lasted about (9) years with everyday usage (I would take the watch off when I worked at my bench doing professional Gunsmithing - for some 30 years). After the watch would no longer run, I ended up sending it directly to Seiko Repair in New Jersey - they charged me an outrageous price, justifying pricing with all kinds of rhetoric as to: HOW detailed the work was, they Pressure test things, Water Test, etc., and returned my watch with scratches on the back, and Crystal (I was not happy, called them, but they did not seem to care), thus NO more Repairs by Seiko of New Jersey!About two months ago my watch repeated the same NO holding a charge, and going downhill. Went to our local Jeweler asking if he could/would repair it, was less than (3) years since Seiko repaired things! Local Jeweler said HE no longer does such work, would send it out to Seiko... cost would be close to $200 for Repair from Seiko - WOW! So I purchased two of the newer Seiko "Solar Watches" SNE031, SNE039, and figured I would have to throw out my now 12 year old Kinetic Seiko received as a Birthday Gift from my wife (kind of a sentimental attachment besides being an excellent timepiece).As a last ditch effort (nothing to lose now) I went to Amazon just to check on parts availability - Boom...enter Swatch Battery.com - You guys had the exact Genuine Parts, a great price, excellent service and shipping. My long deceased father used to repair Watches and Clocks only as a hobby... I have a few of his special tools from 40 years ago. Being a retired Gunsmith, former (8yrs.) Military during and in Viet Nam, and Electronics Technician as my personal professions in life - I am used to working with small components in small dimensional areas, but I'm NOT a watch repairman - so I carefully replaced the (3) components that provide the Power Source - carefully cleaned everything inside and out both before, and after installation - and NO touching the Electronics related parts with bare hands/fingers. My old Seiko Kinetic once again has LIFE, within a short time of wearing, has gone to a full charge in little time, and my favorite watch is back to near new condition. I even polished the crystal with Semi-Chrome paste polish - a happy camper once again.The whole purpose of all this detail is to say - THANKS SWATCH BATTERY. For $18.95, and some very careful work on my part, I saved a sentimental timepiece, and hope it will last for another extended period - and I did not have to spend $200, or throw out this otherwise expensive high quality Seiko sentimentally attached watch product. Thought you guys might like to have this storyline from this "retired" Senior to talk about.

This capacitor was Dead On Arrival. The product clearly listed on Amazon site is Version MZ. What I got was the older and apparently expired version MY. Supplier is using Amazon to dump outdated product. Avoid this supplier. This is the third time I have changed this capacitor which is not easy.1/25 - So apparently this is a correct version. Other jewelers post say a newer version (3023.24T) is the latest. I used an intermittent watch winder that did not get me any where when charging. I then placed it on a Braun toothbrush charger that worked. I cant say the charge rate hurt the capacitor but it is well charged and working. I might suggest having a watch demagnetizer if you do use the toothbrush charger. My compass did not indicate magnetics but? I retract any negative supplier comments above. Product delivered on time.

Excellent quality
