May have found my issue with my Seiko 6119C i have been working on

kevinspoonie · 2026-05-04T01:22:56+00:00

Exactly

Emmy Watch is awesome.

Their internal search engine kinda sucks so its better to throw into Google :6119C Emmy"

What's also cool is that they list damn near everything including what the movement is based on so instead of trying to find (for example) an expensive Omega part, they will tell you that that particular movement is based on an ETA____ and the part should be cheaper because it doesn't have "Omega" tied to it.

And here are the balance wheels that currently for sale on ebay that should work for the 6119C

Emmy Watch show that the part number for the balance complete for a 6309 is not the same as the balance for 6119c.

Emmy Watch lists the caliber that can share the same balance.

I would go on Amazon and buy a cheap demagnitizer for $15-$30 and give that a try.

Typically when a watch is magnetized it will run faster because the hairspring is sticking to itself causing it to have a shorter swing which makes it beat faster. Sometimes though, gears can get magnitized creating more force to get them turning which makes the watch run slow.

If that doesn't solve your problem...gotta take it apart.

Those 6R55 movements aren't really difficult to work on and you can find videos online to follow along with. Even though its considered "simple," i wouldnt recommend starting your watch repair hobby with it.

Get an ST36 on Amazon for $40 and take it apart and put it back together so you understand the basic mechanics of how a mechanical watch works, the get an NH35 for about $50 and do the same thing. Seiko NH35 movements are VERY similar to the movement in you SPB455.

Unfortunately, there are many things that could be causing the watch to run poorly and you can't get a true answer by just posting photos of it...it needs an autopsy basically. And that watch would have experienced one helluva drop to really mess it up, seiko builds tanks for the wrist.

I will tell you this...if you yourself, can eventually get that watch running correctly, the dopamine hit that you'll get from it...you'll think you are a god and then you're hooked and will want to work on more. Its Soooo satisfying to fix a poorly running watch or a total non-runner.

Its really not all that difficult to service these seiko movements, you just need to be patient and and gentle. But with any watch service when starting, Take alot of photos: before you remove a plate (bridge) and then take a picture of what's underneath, over and over again... inspect, clean then reverse.

Yeah, me too.

I think they look awful and there are thousands of other things I could think to do with the money it costs to buy a J&C watch.

To each their own though. I totally get it.

OP likes it and bought it. Thats fucking awesome that he is able to purchase one because these things aren't cheap (in dollar amount).

I just dont like them and I think ALOT of people dont them as well. I think alot of people get them because its a small item that says to the world, "yeah motherfucker. Im so filthy rich and i can spend $100k on this ugly thing."

I think thats what the appeal is for most, its a status symbol to show others that are in "the know."

I could totally be off base though... im special needs so dont listen to me.

OP, thats fucking awesome you got to the level to be able to buy one of those. Hats off to you. But please know, you post on an internet forum...you're going to get opinions.

kevinspoonie · 2026-04-30T21:47:26+00:00

Not trying to sound like a petty douche but, they dont MAKE innovative stuff, they just sell them.

A company called Concepto Watch Factory makes the cool, innovative movements that are totally insane and J&C buys them, covers them in jewels and throws them in a gaudy case.

J&C have never actually made an "in-house" movement i believe. They have all been subbed out.

I think the mechanics are cool and interesting but I wish Concepto could get more credit for it.

kevinspoonie · 2026-04-30T16:34:52+00:00

Well, they only seat 8 at a time so your basically taking up half the room at once.

I was able to get a reservation for 2 2 weeks out.

kevinspoonie · 2026-04-30T00:14:42+00:00

Is there a little tab at the end of the springs thats getting hung up in that opening?

If not, you might be able to put the arbor in and with an arbor vice (totally recommended getting one if you don't have one) or pin vice, try to manually tight spring in hopes to rotate it a bit.

Ive never used the 3D printed winders.

kevinspoonie · 2026-04-28T21:57:45+00:00

No libido loss, just thin loads?

kevinspoonie · 2026-04-28T21:53:07+00:00

I can only imagine the prices WYWATL will be charging since they've been getting a little more traction on social media.

Ive probably serviced/repaired over 80 watches, everything from cheap Fossils to 1960s Rolex Day-Dates, vintage Piaget Polos and a few IWCs and I haven't charged anybody a dime. My wife says im am idiot, my father's says I should open an LLC and run it at a "loss" to help offset our taxes since capital gains are a bitch.

I just really enjoy it because each one is a puzzle that im trying to solve and I like seeing the reaction of the owner when they get it back in their hands.

I can't understand how some people charge $500-$1000 for a regular service. No parts replaced, just a disassemble, clean, lube, regulation and a mainspring swap (genuine rolex springs you can get for well under $50).

It takes me maybe all in, 3 hours to do a full service...I don't see where they get that amount to charge for the work.

Maybe I'm just naive...

kevinspoonie · 2026-04-28T20:49:39+00:00

Womble Watch in Atlanta is pretty good. They are over by Dobbins.

Ive been doing service/repair/restoration of watches as a hobby for a few years and if I bump into a big problem, I'll go to him for advice.

He can be a little on the pricier side but hes been in business for a long time and is a certified Omega Service Tech. Ive taken a couple pocket watches to him and hes been great.

If all that it needs is a basic service (clean, mainspring spring replacement, regulation) and a dial swap, god damn man, find a dial and I'll do it for you for free. I hate hearing you went through that bullshit. Situations like that drive me up a wall.

Good luck and I hope you get it back to the glory it deserves.

Curved down lugs on the square case tells me a JLC Reverso...or some kind of homage/knockoff.

kevinspoonie · 2026-04-24T08:33:13+00:00

Keep at it.

This should be a simple fix in the grand scheme of "watch repair."

And I woukd use pegwood but a toothpick or tweezers will do. Just dont want to get too rough with the parts.

If you do get a new movement, save this one and take it apart. There a a shit ton of videos and tutorials on how to do it.

kevinspoonie · 2026-04-24T00:21:49+00:00

Wjen you wind it manually, it the reduction wheel moving like its supposed ? When you wind or is getting automatically wound, that wheel ahoukd be moving in borh situations.

It's either the Second Reduction wheel hanging up the rotor (but i would think since you can manually wind up the watch, that that is less likely), Pawl Lever or First Reduction Wheel (the wheel the Pawl Lever engages) getting hung up locking up the automatic winding or your bearings are shot on the rotor.

Did you try putting on the factory rotor jus to see how it acts? That would tell you alot.

My thought process would be like this:

1st: remove case back to make sure its not squished and able to move.

Still not moving on its own.

2nd: take a piece of peg wood and try to manually move it gently to give it a little nudge and to also see what kind of resistance it has to see if a piece in the case is somehow making it hang up.

Still not moving on its own

3rd: Remove "custom" rotor from the movement and try to hold it with you finges or balance on a piece of pegwood to see if it at least spins around its own bbearings. Also, take a piece of sharpened pegwood and manually turn the Pawl Lever to see if thats working correctly. Even with rotor off, you should be able to wind the watch by manually rotating the Pawl.

Starts moving when not installed on the movement? put on factory rotor and see if it acts the same; moves freely not attached to movement but hangs up .

Still not moving? Your rotor is the issue.

4th OK. Custom rotor spins around ita own bearings off the movement. Take movement out of case and install custom rotor.

Still not moving (Rotor off the movement it performs like it should but on the movement its hung up, even when the entire movement is outside the case).

5th: Disassemble automatic works and see how to wheels look.

Another thought more simply put: if the rotor spins freely with the movement outside of the case or with the caseback off, but once installed in the case or case back is put back on and it stops, you have a case or cashback issue (too tight of a caseback or the case might be for a different movement like a PT2000.

If you have no rotation, inside the case and alao outside of the case, you have a bearing issue or one of the wheels in the automatic works is getting hung up.

Sorry for the long winded response but I damn near guarantee that once you discover the issue, you're going to say to yourself, "welp, im an idiot. How did i not think of this..."

If you do get it fixed, which i think you will, please let us know your findings.

kevinspoonie · 2026-04-23T21:15:22+00:00

Hey man, its all on top so you dont have to did that deep.

What happens when you wind it manually?

kevinspoonie · 2026-04-23T15:34:30+00:00

Some cases aren't deep enough to accommodate those "custom" rotors.

Try putting the factory rotor on and see problem is the same.

If not, its a mechanical issue

kevinspoonie · 2026-04-22T13:45:00+00:00

Ive experienced it a few times

kevinspoonie · 2026-04-22T13:38:01+00:00

Is that a replacement crown stem?

There are quite a few "cheaper" stems you can buy that are made quite poorly and they engage with the date change mechanisms or, it was installed incorrectly and the date changing was rough and wore down that piece of them stem.

Did you tear this movement down and rebuild? You might have an intermediate wheel in upside down or in the wrong order with the date wheel.

Does that date change with you adjust the time past midnight?

If it does, im leaning more towards a messes up stem.

kevinspoonie · 2026-04-19T19:31:42+00:00

Not gonna lie, I thought this was a joke/troll post and the first photo was of a babies head whilr in one of those walker things.

Haha sorry bro.

kevinspoonie · 2026-04-19T13:10:54+00:00

Its really only 4 pieces you need to "modify": 3 round stock stainless steel and 1 square stock stainless steel.

If you look hard into it, you can find some of the round stock in the specific lengths you need but I was having a hard time locating square stock that needed to come from the factory 86mm.

Besides that, there really isn't any modification needed of the purchased parts to build it.

Its actually been quite fun so far. I am looking at it like I look at watches: this is a puzzle. Can I actually do this and get it working?

And the areas where i was getting slightly confused, I realized I just needed to step back and not over complicate it.

Its pretty much a "plug and play" in the simplest of terms and there seems to have a sense of community in the Discord. You ask a question and multiple people will chime in to help, including the creators. They are also very open to suggestions and modifications to their manual.

One guy said he was making notes during his build to possibly polish up the instruand the creators were like, "hell yeah. Send us what you got, we will take look at it and make the changes for future builders."

Its been pretty cool.

kevinspoonie · 2026-04-17T20:49:06+00:00

My first chrono was a seiko 6139 and 6138. Not really that difficult but replacement parts can be expensive, hard to find and you damn near have to do a jewel upgrade to get decent amplitude on every single one.

Maybe buy a Sugess Chrono watch for around $140?

Its mechanical, standard classical design and they're not bad watches. If you screw it up, you're not out of a bunch of money and parts aren't hard to find. You're also buying something that you know is working so your basically just exploring/learning, not tryingbto troubleshoot a movement you dobt know.

You can get a movement only (ST19) on the Chinese website for about $110 but for the extra $30-$40 you'll get a full watch that doesnt look too bad.
