Hi everyone. I’m really starting to get disheartened because every single piece I work on after cleaning reassembling and everything else ends up having extremely low amplitude. I have watched all of the courses made by Mark and a plethora of YouTube videos but still cannot figure out what I am doing wrong it seems rather consistently. Working on many Seiko movements it seems that when I take them apart and put them back together after a thorough cleaning using rather expensive watch cleaning solutions in an ultrasonic cleaner, I cannot seem to improve the performance of the time pieces at a maximum and normally can’t get them running at all. Has anyone else had gone through this? 
 

I find it fascinating and relaxing at the same time. I am starting to believe that maybe I don’t have a necessary skill set to do this. Can someone please chime in and let me know if they’ve experienced the same things and also what they did to remedy the issue. I feel like no matter what I do everything doesn’t work. I have ordered multiple beautiful time pieces online and while they come in relatively working order they definitely need servicing. However my actions always seem to degrade the performance by having extremely low amplitude. Every watch I work on a start and then stop when I move it to another position. I’ve tried everything, inspecting the jewels, Oiling of the parts with very expensive Mobius oils, and also ensuring that I sparingly do so. Please advise I really would appreciate any input here.

Welcome to the forum.

Most friction in escapement is at escape teeth running on pallets. 

Put a bit of Kerosene or diesel fuel on escape teeth, you would see surprising jump in amplitude. 

Fork arbour and it jewels should be clean and unlubed.

Check all end shakes, most important of all on balance staff.

I work on hairspring once installed, to get the coil level and flat, even on new balance completes.

Do you remove shock spring, end stones and chaton, gives additional bath and peg?

Do you makes sure impulse jewel is in beat?

I stick balance pivots into a tooth pick, turn the tooth pick, add a bit of lighter fluid as I turn.

Drop the flat side of end stone on a piece of card board pour a bit of lighter fluid on it whilst you put you finger on the endstone, scrub the flat side on the card board, nothing short of a perfect glittering shine is acceptable. 

Examine balance jewels under high magnification.

Stay tuned and ask questions.

Well you have had good advice from Joe to act upon,  Do you use or have a timegrapher ?  do you test the watches before treatment and record the Amplitude and again after and what sort of loss values do you get.

Your watches should run reasonably even when unlubricated, if they are in good condition. The most common issue I can think of is bent hairsprings (especially relatively soft Seiko ones).

and don't be disheartened.  I know it's tough at the beginning and also if you've had a run of fails.  But the highs far outway the lows.  Stick with it and you will be rewarded.

Usually what I like to recommend for beginners is to purchase the Chinese clone of a Swiss pocket watch movement. The same one that Mark uses in his course. Then a timing machine today is inexpensive at an absolute must have. Because then you can take your brand-new movement and check it out. Then practice taking it apart putting it back together and verifying that still running the way it was before you took it apart

Then as a minor reminder cleaning doesn't fix all problems. So if you're Seiko watches were running before and you had a timing machine verified that then they should be doing equal or better after cleaning. But if they were having an issue before cleaning may not fix the issue.

Then expensive cleaning fluids like professional fluids? They clean really well but you only want to have them in the Cleaning solution for a couple of minutes especially if it has ammonia in it. Professional watch cleaning fluids clean really well  that going past a few minutes they start to etch things and that does not make for good running watch.

Then looking at your title no amplitude means the watch is totally dead? Low amplitude means what to you? The reason I ask is Seiko's classically have very low amplitudes. It's just the way they are made and if you think cleaning them you're somehow going to make them better it isn't going to happen. This is where it's back to a timing machine you need to have a before and after to see if you're having a problem.

I use the ultrasonic cleaner for a short while 3 minutes with the cleaner (Zenith Radiant 777 Ultimate Watch and Clock Cleaning Solution) and then 4 minutes with the rinse (Zenith Drizebrite Watch and Clock Final Rinse). 

Additionally, I've found using a microscope is an excellent way to position the wheel pinions into the jewel holes and use an application on my phone as well as the Tg application on my computer for consensus regarding timing. As it turns out now, it stopped moving at all. 

What I am seeing is that when I work with Seiko movements, tightening the screws on the wheel bridge causes the movement to stop. I am not talking crazy tight, just taught more or less. Loosening the screws so they still move freely allows the wheels to run (but I don't feel comfortable leaving them this way as they most certainly would work their way out over time).

Is there something that can cause this? Is this specific to Seiko movements? I can work on the Chinese clone movements 6497 and 6498 without any issues.

Thanks again, there is something so relaxing about taking these apart and reassembling them. I appreciate your time and help!

Is this all Seiko movements to work on or only one Seiko movement?

Then yes the screws are supposed to be down tight.

Had to do a quick read through the entire discussion and

If you look at Seiko for instance your plate is covering quite a few wheels and it is thinner then the 6497. It's possible if you push too hard when you putting the wheels in that you may have actually Bent the plate. Another thing that can happen is if the watch doesn't have jewels for all the holes and you push hard on the plate to can actually raise burgers possibly in the hole itself.

Then for this discussion when I went back reading it quickly we can see a generic pattern that you're having a problem with all of your watches. What makes it sometimes easier to troubleshoot individual watches because the unfortunate common problem then in all of your watches would be you're doing something wrong.

Some might be helpful to just pick one problem watch and post pictures and whatever we go through that one watch rather than a generic whole bunch of things otherwise we end up with lots and lots of ideas that may or may not be helpful for the particular problem.

So in the particular example I quoted above take the balance wheel out take the pallet fork out. With the screws loose manually wind the watch I assume the gear train Spins nicely? Then adjust the screws tightening them a little bit do it again and keep going until it stops spinning. Then I find my finest oiler works really well go in and check the end shake of all the wheels see which one is tight. Then once you've done that will look at the problem again

How about letting us work with you from start to end of the next project you pick up. 

Not a bad idea, ha.      what do you say?

I have subscribed the lesson 3 from Mark's lessons and finally figured out what I was doing wrong. Somehow during the cleaning process (I reattach the balance complete to the main plate before washing) the impulse jewel is not in beat at all. Mark's excellent courses helped me go step-by-step through the diagnostic process and I was able to rotate the collar and align correctly to get it in beat.

Nucejoe had originally mentioned "is the watch in beat?". I initially dismissed this as "how could I tell since it isn't running?". Goes to show that any advice is worth a try and not to get ahead of the basics.

Thank you all! My faith is restored and I think I have found a new lifelong hobby!

Glad you've found a solution. 

Here's a thought: check out the 404 Club. I was in a very similar position very recently where it seemed like everything I touched ended up in a worse state than it started. I've been playing the 404 Club game though, and if I have no more than $5 in any given failure it doesn't hurt my feelings all that much. I can even write a lot of them off as "probably worn out and borked up before I got it anyway" if I'm really feeling down about it. ? Save the watches you actually like/have some money in for when you've managed to improve a few.

A test to find out if impulse is in beat when movement isn't running.

- Release all barrel power through the click so fork wont be charged with any force to deliver to impulse jewel/ pin, then obviously balance would not run but stops. then turn balance wheel manually, by tweezers etc, whilst you keep an eye on fork, at some point fork starts to move, which indicates impulse has come to engage with fork's crown/ horn , you can also see pallets engaging with escape wheel.

Impulse jewel/balance wheel  is in beat if impulse jewel is inside of fork horn as balance wheel comes to rest( without any external force acting on oscilator  including the fork).

This is enough for the escapement to do its job and energize the oscilator, though some error is inevitable, timegrapher will then show you the beat error.

A step furthur is to observe pallet do a drop, that is where you want fork to deliver energy to impulse jewel so to maximize the amplitude.

We all are learning here, without asking you wont get a response.

Good luck pal.

    • This was what I was afraid of. The movement is not one of the generic black square modules. Remove the movement from the clock and try prying it open very carefully, without breaking the plastic tabs. The plastic might be brittle from age. Clean the wheels and check the battery contacts for corrosion. Check the PCB for bad solder joints. Take plenty of photos along the way.
    • One of the problems with trying to Photograph Phils things are that his enjoyment was building these things so they tended to E falls on what will see if I can find some earlier pictures or any pictures I wasn't even sure because I was looking for that specific picture for somebody else and even it got the last version and that would have been the last version. You will note that he put the indexing on something that he could unscrew it or whatever and it can slide back out of the way so the rest of the lathe can be used as a lathe. With the lathe cut are actually coming down from the top I was there once where he demonstrated how to cut a pivot with the setup it was really beautiful. Older set up if I remember it's not a worm gear assembly in the thing in between the stepping motor and the holding block I believe this particular one was like a 100 to 1 gear ratio. Earlier version with watchmaker's lathe. Even looks like he is the watchmakers bed and then switch to something he made. Then I do have other pictures and things of the rotary stage in use. In the raw so if you tube videos here is an example of one were somebody's mounting a three jaw chuck. At one time there were available on eBay they were not cheap but if you're patient like I was I found one cheap on eBay. After you watch the video it look at his other videos he is a whole bunch of other examples of the same rotary stage. That I do know there are other pictures examples and possibly videos you just have to track them down. One of the minor issues of finding this particular tech sheet for the unit is I believe it was a custom manufacturer and the company change their name but I remember the new name here's a link to the company https://www.ondrivesus.com/rino-mechanical-components                
    • Escapement adjusting always interesting and depending upon the reference always confusing. Okay maybe it's not always confusing but it does lead to confusion. I have a PDF below it's actually a whole bunch of separate stuff including a hand out that came from a lecture that's on you tube. Then from that we get this image Consequences of doing things especially if you do things out of order or you do things for the wrong reason. Oh and even if the watches working I made the mistake one so showing my boss how tweaking the banking pins on a full plate on the timing machine made the amplitude get better and now he thinks that's what they're for and I don't think a fully grasped exactly what horn clearance means. Consequence of doing things. Notice what it says about opening and closing the banking pins and total lock? So yes I've had that on a full plate where it won't unlock at all and that's the banking pins or a combination of things basically. So banking pins unfortunately get moved. One of the ways to tell if it's been moved is the look straight down at the end of the fork with the balance wheel removed. Power on the fork push at the one side look at it push it to the other side also look at it and compare anything with the center reference the balance jewel and see if both sides of the same. No guarantee after the same there in the right place but at least are the same typically when people play with things one side will be way off from the other because they had no idea what they were doing at all because of course it's a full plate and you really have to paying attention and even then there's still hard to do. Then the other thing that comes up like it shows below is people often adjust the banking pins to do all those other things as opposed to horn clearance which is all that it's therefore and maybe bonus Guard pin clearance although you're supposed to deal with the guard pin is a separate thing like single roller gets bent in Or out or sometimes physically gets moved in and out. Some full plates older escapement's typically pallet forks held together with screws and you can actually unscrew and move the entire assembly in Or out more complications to deal with.     Escapement handout wostep nscc.pdf
    • If he was much younger and some sort of sports player it wouldn't be a problem. They would be in there and doing surgery and he'd be back on the field in no time. Unfortunately when you get older little things are bad and big things can be really bad so not good at all.
    • Where I work everything incoming watches whatever detailed descriptions are taken entered into a computer program and photograph of each item. Then ideally although it depends on who's doing the paperwork detailed descriptions can be quite good other times there lacking. Like I really like it with pocket watches if they would record the serial number it avoids confusion later on. Then when watch repairs are completed that is also entered in. It's one of the amusements I learned when I was in school instructor had a shop and commented about the important aspect of keeping detailed records of repairs. Because oftentimes a customer who got a new crystal will come back later on when the watch doesn't work and expect you to fix the entire watch for free. Then you can remind them that they just got a crystal. Strangely enough that keeps coming up or occasionally comes up where I work now. One of the problems of using the service marks on the case is that in the case of pocket watches oftentimes that's not the original case. Then case marks? What I was doing warranty work for a company I used to describe a code number in the back of the case and it would tell me the next time I see the watch that basically what I did I made no attempt at keeping track of customers because we had literally thousands of them I think they sold 30,000 of these watches and they would come back by the hundreds because they had a lifetime warranty. Yes that's a story all of itself but I would put a code number that would reference what was done to the watch the last time and think I had a date in there somehow so it did tell a story if you knew the code. Another shop I once worked out the number would reference the page in the book. So other than knowing we had been in there you would have no idea what happened because you have to go look at the page in the book to see what happened. Then the problem of how you examine a watch you should examine the watch in detail every single time to avoid complications. Although on vintage watches and this is a of amusement I have at work when people ask something and I say of the watches done when it leaves. This is because on vintage oftentimes problems won't show up until the watches much farther into the repair like it's now running and you discover things that you can't discover before because it wasn't running to discover them that also become sometimes difficult to have exact rigid prices are estimates of repairs or in the case of a pocket watch you may not find out if a casing problem to later on when you case it up in the watches running. I was just thinking for all those people that would like to leave a mark maybe you should learn to do what some of the past watchmakers did? Leave a mark but leave it in such a way that no one will ever find it? Typically not done for repair purposes but done for other reasons like identifying it's legit. I have a friend with a Gruen watch and one of the Roman numbers the bottom line that just looks like a line under extreme magnification actually says Gruen watch company or something equivalent. So here's a link showing how to mark your watch without being seen although that's not the actual title. So if you can learn micro engraving you can engrave the watch someplace probably just about any place you just have to remember where you put it. https://cnaluxury.channelnewsasia.com/obsessions/how-to-prove-if-watches-are-authentic-secret-signatures-182516
