seiko 5t52b movement not working

[adiorio110]

Hi All

I am a newbie ...If fact still waiting for my watch course to arrive(should be here Friday). In the meantime I built a little work bench and purchased some tools(posted a few pictures in introduction forum). 

Because I am anxious to start tinkering I decided to replace the battery in a seiko 5t52b movement. I replaced the battery, no dice, so I shorted the AC to the battery positive, still no dice. I know I may be getting ahead of myself but what should I be looking at next.

Thank You

Anthony

There is not much that you can do, except checking coil resistance and pulse output. You need a good tester (low voltage) for that.

Thank you for the manual I registered on that site seems I have a few seikos that have the same problem. The manuals section should come in very handy.

I have to order another battery. I could have sworn when I tested it was good ..There is either a crazy drain or I made a mistake. Battery only has .4 volts. So first I'll try another battery. when testing the coil resistance and pulse output I assume the battery should be in the movement. sorry for my complete ignorance.

In my opinion most Quartz movements are not worth tinkering with. I would take measurements of the movement and see if there is an equivalent replacement. 

This table could be useful

Coil resistance is without battery and even with coil removed.

I hope you used plastic tweezers to handle the battery?

Gotta agree with Clockboy on this, there are exceptions depending on the diagnosis/repair, some of the older Seiko quartz chronos are getting harder to find NOS replacements. The newer kinetics are pretty high priced too. Your 5T52 looks like a 7T32, but that would be a guess and case measurement would be critical. Also check the pushers for dirt and sticking.

[rogart63]

Looks similar to the 7T32/34 movement. Your movement isn't the cleanest is have seen? So maybe there is dirt an rust inside? 

Sound like something is draining the battery? Probably a shortcut? You can lift the circuit board and see how it looks?

Hi all

And thanks for the replies. I am waiting for a new battery before I go any further with the Seiko. In the meantime I received my watch repair course a day early. A donor watch also was delivered, a side wind lever set Elgin. The watch is running and seems to be keeping good time. To be honest with you I really like it and hate to take it apart, it even has my first initial carved into it, but I guess some have to be sacrificed for the better good. Wish me luck. Here are a few shots of the victim.

That's a nice pocket watch that you have picked up.  

Can I suggest that you delete the above post and start another thread relating to this one and keep this thread for information relating to the Seiko.  

It helps others when searching for threads on specific watches.

I would be glad to but I can't figure out how to edit or delete post on this forum.

Also I see you were the one who tested the Lamp  8015LED-U I would like to ask you a few lighting questions. Should I start a new thread or should I post in the one already started . It is an old thread started 2 years ago last post was last year.

As a newbie how do you feel about painful lessons? In other words if you destroy your first watch are you going to regret it? As Geo commented you have a nice watch that's running more than likely it will not be running after you take it apart and try to put it back together. So this is a full plate American pocket watch things work just a little bit differently on these. They just tend to be very confusing for new people and not always fun to work on especially when you go to reassemble them. If the watch wasn't running it was broken I wouldn't care but I just hate to see running watches destroyed in the name of learning purposes.

When I look at the copper contacts in your image, it seems they are a bit corroded

I don't think that postings can be deleted? Probably that would be useful on some cases.
I agree wiith others, better leave the Elgin alone and get something else to start learning.

I appreciate the advice,  But I never start anything thinking I will fail at it. I WILL put this back together again and it WILL work (that was just some positive reinforcement LOL). 

• Another point of view might be if  I took apart a watch that didnt work and put it back together. How would I know I did it right. I am not at the point I can diagnosis whats wrong to fix an otherwise broken watch.

That's a good attitude that you will need to keep if your going to do repairs. I would agree that a running watch is better to work on, but you don't get any diagnosis experience. Before trying your hand at teardown/reassembly of a 100 year old pocket watch, you will gain more knowledge working on some broken cheaper donor movements.

What if you accidently bend that hairspring?, It has happened to all of us, your going to feel terrible and PO'd at yourself, plus added cost to replace/repair. Have you priced a good staking tool set? Cuz that's what you'll need to replace that bad hairspring. Put the Elgin away for another day.

I already did some work on it ...But I think I'll take everyones advice and look for a junker

OK I picked up a scraper any one have any info on it. (maybe not but I'm Looking)

Having worked with beginners and their watches I sometimes think a better approach would be to let you work on great grandpa's family prized heirloom watch. More than likely are going to destroy it you'll remember that for a long time. I can strangely enough remember all the bad things I did when I started watch repair. I can still hear a jewel cracking the pivot wasn't where it was supposed to be it was a really really pretty jewel in a pocket watch.

 

So start off with a junk watch even a partial watch. Practice taking it apart and putting it back together practice a lot look at what you're doing see if you break anything don't worry if you break something we all did. I can remember being in watch repair school we were given partial 16 size watches to practice with. They were partials because the balance was removed and they were actually a timing mechanisms there's no main spring on these. The balance wheel doesn't get put on the watch until much later on when we can safely take the train apart without destroying it. So practice taking apart putting it back together getting bored asking the instructor what to do next. He suggests do it as fast as you can. So several broken pivots later and I still remember the lesson. Everyone breaks things when they start.

So another option break something that you could replace. It's quite a pleasure when the watch you took apart comes back together and runs. So what makes a really good training watch movement for newbies is something big and something that we don't care if you destroy. So a 6947 Swiss pocket watch cloned by the Chinese they show up on eBay regularly. So big easy to work on if you destroy up by another one off eBay. Then link below disassembly reassembly visually can see what you're doing. Notice there is a variation in the number 6497-1 6497-2 Basically the same except frequency first runs at 18,000 beats per hour the second at 21,000. For training purposes that are both the same I wouldn't recommend taking the mainspring barrel apart. Also don't play with the balance jewels yet especially if the Chinese they skip to step and we should probably go over that before you do that it's not really something you need now in a way definitely not for pocket watches.

Also attached is the tech guide and manufacturing information sheet. Both of them together have a lot of technical information.

I thought the watch I purchased was cheap enough.. But your right I don't want to wreck it. Only cost me 60 bucks. I found another watch (movement only) it also runs but it is exactly the same as the one in the course I am following, so that is a big plus. It is a side wind lever set, Only cost me 43 bucks I could not find a non working one for a better price.

Yes.
That made remember when I brought a nice jump hour pocket watch for repa
ir, I must have been 11 or so. It didn't took long for the guy to figure out that someone must have messed with it, now guess who? [emoji52] That was so long ago that watchmakers were a common business, as he had shop the next block from ours. That watch might still be with the family but Mom is not so willing to go check the safebox at the bank, easier would be have Dad cough up the English cased Rolex, thing that for the right money he could even do [emoji2]
Going back to more recent times I then tried to put apart for no reason at all a battery Swatch, having no screwdriver smaller than 2mm, which seemed very small at that time.
And finally to the present time of placing Seiko parts upside down and collecting a cemetery of balance and hairsprings.

[adiorio110]

Holy gears from hell batman!

Ok. So as the movement is useless as it sits and I was a little bored I figured I'd take a peek inside. I think I met my finally met my match. Does anyone knbow where there might be a step by step guide for this movement?

step 1,  don't try to learn on  battery watches.    step 2 ,get some plastic tweezers.   step 3 ,read a book or watch a video on the particular watch you want to learn on. ; 1,2,and 3.-- simple.

Adiorio,

From the picture it looks like the watch has 3 separate stepper motors each having its own gear train. If all three motors are dead the problem is probably further back in the circuit. Check to see if you are getting a proper voltage to the computer chip. Then check the driver output from the chip to the stepper coil. An oscilloscope could be very helpful to trace out the problem as it can show a picture of the actual pulse that drives the steppers.
