Hello everybody,

I have this watch that has become the bane of my existence but I'm still determined.

I have talked about this watch in previous two posts so I'm going to make this a shorter post. (https://www.watchrepairtalk.com/topic/24867-dilemma/#comment-204116)

I found a movement with good balance complete in it or so I thought, the regulating pin part was broken so I changed the balance cock with one of the 2345423 that I already have.

the movement is clean the train of wheels runs so smooth even the slightest puff of air can make the wheels turn, the pallet fork springs back and for, the balance wheel's pivots are intact, the hair spring in a good shape.

BUT THE DARN THING DOESNT WANT TO RUN!.

the balance oscillates for like 5 seconds, sluggishly, and then stops.

I'm so mad and lost I do not know what I'm going to do know.

I'll attach a couple of photos of the balance complete but its low quality because it was late at night and I was so annoyed when I took those photo.

Anybody has any idea what's happening?

How does the balance run without the pallet fork in place? 

The pallet for is in place and springs back and forth when I tap it with the tip of my tweezers, I never said it's not in place.

I asked how freely the balance runs without the pallet in place.  Remove the pallet fork and check for freedom of movement of the balance wheel. 

Oh!

Sorry misunderstanding.

I don't know how this never crossed my mind, I usually do this every time before assembling the movement.

I'll try once I go home today.

Did the balance run good with the old cock?  if not,

1-Check if the roller table rubs on fork horns, in case you can,t verify anything visually, remove the fork .

2. Check end shake on balance.

3. See if H/S rubs on balance spokes or on underside of the cock or the coil fouls itself.

Once you had the balance detached from the cock, you had a chance to check pivots for shortness  or bent or chipped pivots? You ought to check these now.

Are you sure jewels in the setting are clean & fault free?

Good luck

Hello,

Sorry for the delayed response.

I've been trying to get watch to run for a long time but no matter what I do it just does not want to go.

I even got a working movement in a good condition but as soon as I serviced it it stopped working properly so I decided to throw out everything that reminds me of it for the sake of my own sanity.🤣

When you have really tough setbacks, it is easy to get the feeling of wanting to give up and many times I have given up and thought that enough is enough, and I think that can be a good thing even if it sounds contradictory. Sometimes you simply have to let time pass before you are ready to try again or try something new. When the brain have calmly and subconsciously processed the problem, you automatically get the urge to make a new attempt and not infrequently it leads to success, or at least getting a little further.

You will succeed! Sooner or later! 👍

What are you using for cleaning them?

I had problems with the first movements I rebuilt barely running; that was down to the cleaning method I used (lighter fluid then IPA).

As soon as I started using proper cleaning liquids - L&R #111 & #3 - that problem just went away. I can only guess that the old dried oils were not properly removed by the original solvents.

I'm using pharma grade 99.99% IPA, I do initial cleaning in small bowl with a brush and then I run them three cycles in the ultrasonic cleaner.

I do not usually get any problems with cleaning, I think this specific watch is just not meant to be.

Are you also cleaning the balance and pallet fork with IPA? IPA will dissolve shellac (i.e. roller jewel on balance and pallets on the fork).

I use lighter fluid for balance and pallet fork and then I rinse them in IPA.

While IPA does in fact  dissolve shellac it doesn't happen very quickly so it is safe to leave the parts in it for a few minutes.

IPA us good for a rinse but not good as a cleaner. 

Generally correct but I'm just a hobbyist and getting cleaning solutions here can be very expensive here this is why  I use IPA and to be honest I have never had any problems with cleaning before, I inspect the parts under my USB microscope and everything usually looks squeaky clean although I do get some congealed/dried oils sometimes that are not dissolved in the cleaning process so I reclean the part and then I'm good to go.

Hi Ammar,

If You need real help, You should do what @RichardHarris123 asked to do - the free oscillations test when balance is in place but the pallet fork is not, and write here the result. You must turn the balance to 180 degr. and release it to oscillate till full stop, and count the number of free oscillations. About 100 is expected when balance is OK.

It is no good idea to mix the bridges and cocks, as they are actually parts of their own main plare and are mashinned together with it. So generally it is recommended to choose the movement in which the good balance came with. You can use the original movement, but then the original balance cock is to be used. Mixing hte parts sometimes leads to problems that even for experienced watcmakers is hard to find and to solve.

Ok yes, that should be fine. 

Are you using fresh lighter fluid for the balance alone or are you mixing with all the other parts? 

Just a little bit of oil (dissolved from all the other parts) can remain on the hairspring and make the coils stick to each other. I suppose this may be removed by the IPA rinse, but maybe not fully.

Exact same materials and exact same problems!

 

IPA is not a good degreaser or oil residue remover. Something like paraffin should work better for the initial wash.

Also, as I discovered, IPA and lighter fluid are so different they do not even mix well!

See the photo - a few drops of each in a flat plastic lid, and after a couple of minutes there is still a clear, sharp line where the two different liquids are in contact but staying separate!

Lighter fluid on the left, IPA on the right - and the contact line between them in the marked area:

When talking lighter fluid we usually mean some type of processed naptha, distilled. A petroleum based chemical that acts as a solvent. IPA also known as Indian Pale Ale is alcohol based.

I was using lighter fluid only, for the main washing part, then using IPA (the 99.7% grade) as a rinse. I believe what was happening was the IPA never really mixed with the lighter fluid that coated the parts, so the crud dissolved in that was left as residue after everything evaporated.

And IPA mixes with dried oil & grease about as well as it mixes with lighter fluid.

I also know I've not had a single "sluggish movement" problem since switching cleaning solutions.

Hi,

I did do the oscillations test on the original movement with a couple of good balances but they are not turning smoothly, I'm starting to think that this is a weird variation on the movement because I could see subtle differences between the original movement and the other hundred movements I have.

now that I've lost track of which balance belongs to which movement and to be honest I lost interest I do not think I'll touch this watch again, not in a long time anyway.

I'm using fresh lighter fluid and IPA specifically for the balance, I discard the fluids and use new fluids when I clean another balance.

@rjenkinsgb I'm not saying that Lighter fluid and IPA are better than professional purpose made watch cleaning solutions I'm just saying that those fluids are giving me good results.

I never mix lighter fluid and IPA I always dry the parts on one of those usb carbon heating pads after every cycle.

This is OK, but have in mind that every time when the balance is replaced and the free oscillations test is not OK, one should not simpy conclude that the balance is not good for this movement. The good watchmaker will start investigating what is the reason, the same way if this is watch with some problem and the problem has to be diagnosed. Usually some slight adjustment is needed to bring the things to normal, but one will never know what to do if He doesn't know what is the specific reason for the specific problem. In case of balance, the usual reasons are incorrect free plays in bearings - radial and axial, balance rim rubbing on something (pallet cock, cetner wheel...), balanse arm/spokes touch the regulator or hairspring stud, the bottom of roller touches the main plate, all the hairspring caused problems... So one must put the loupe ont His eye and observe and investigate the balance behavior and all the critical points that may cause problem. There is a way to test and confirm/exclude all the possible reasons. Gaining experience and knowlages about the pivots/stones, hairspring, escapement function and behavior eases the process alot. Untill then You can ask here what to check next and You will receive good advice.

OK, leave the watch alone for some time. When You decide to start again, You can count on support here.

My point is (and I've just done more tests to verify this) - IPA does not work well as an oil or oil residue remover. It's probably not removing the dried residue from the initial wash.

 

I tried the adjacent drops test again, with 3-in-1 oil and IPA, and the two do not mingle - it gives the same very clear line where the two are in contact.

Ethanol, by comparison (denatured alcohol) flows in to the oil and dissolves it.

 

I'm not saying you should use the commercial cleaners; what I'm suggesting is stick to lighter fluid only for both initial clean and rinse, or rinse with ethanol rather than IPA. Or start with paraffin / lamp oil & rinse with lighter fluid?

The IPA probably works OK if the movement is pretty clean to start with, but if there was a lot of old oil the initial lighter fluid wash probably left a small amount of gummy residue, that the IPA never removed.

(I admit I was surprised with the effect of the change to different cleaning liquids, and now even more surprised when I tried that test with the drops and found the IPA just did not mix at all!)

 

I'm going to try other fluids such as paraffin & see how it compares to the commercial stuff, as that is far cheaper - £12 for 4L locally, or £36 for 20 litres (as Kerosene) on Amazon, compared to the dedicated watch cleaner at around £10 per litre.

If you are using the naptha and IPA method of cleaning, which can produce good results, there needs to be a rinse between the naptha and the IPA in distilled water. That will get rid of some of the problems of the naptha sitting on top of the IPA, which will coat the parts as you pull them out.

Well this is very interesting, I've always thought that IPA is a strong solvent not only for watchmaking.

We do have loads of Ethanol at work I'll get some and start cleaning with it instead of IPA and see the results.

Ok I'll take this note in consideration, we have an RO water treatment unit at work so I can get as much I want.

I always become weary when specific numbers are specified. Amplitude comes to mind. I think the time would vary quite a bit depending on an array of factors such as the weight and diameter of the balance wheel. But "about 100" seconds (I assume you don't mean oscillations) sounds in the ballpark for any common Swiss wristwatch movement. I agree.

It's absolutely mesmerizing to see the balance wheel oscillate for a hundred seconds, but what I usually do is just give the movement a light twist while in the movement holder and then study how the balance stops. If it doesn't come to a stop completely seamlessly there's something that needs attention. Any kind of abrupt stop, even when the oscillation of the balance is minimal, indicates an imperfection.

    • The watch is from 1990 and was serviced just once around 20 years ago. No idea if the mainspring barrel was ever opened or changed before now.
    • Interesting but I think we have a problem here? We probably need to split hairs on a definition problem. For instance take a real Rolex movement put it in a real Rolex case but not the one it came in take a real dial real hands and make up a watch that is 100% real and what exactly is this? If you send your Rolex in for servicing and anything's been changed at all from what it was when it left the factory Rolex will be unhappy and remove all offending components. This does become a problem of people changing things because they think it's their watch and they want to have a different dial Lord diamonds the bezel or whatever words Rolex sees all of this as evil and bad as far as a Intel Rolex only things the watch is legit if everything is exactly what it was when it left the factory and nothing's been changed including the stem everything asked me Rolex original or their very unhappy about its existence. Then you think about a fake watch what is its real purpose? Well its real purpose is to make money for somebody and fool the customer. So all the watch has to do is look pleasant on the outside and inside can be anything. Typically nobody's going to see inside. So typically anything that's not legit counterfeit movement etc. why would someone spend so much time and effort making it look just like a real Rolex when there's no need to? Unless of course you have one or two movements to impress somebody with this is what's inside your watch but even that is problematic Now we don't end up with I've interesting problem that troubles me where I work. The owner will offend a cage your watch by looking at it carefully with a microscope the timing machine etc. and he will point out all the things that he feels are not appropriate correct or whatever for your watch. But in my example above of mixing and matching legitimate Rolex parts he wouldn't necessarily be able to tell. The problem I have with this is it often times things like his claim to telling a counterfeit is look at the second hand the quality of the secondhand is not as nice as a legitimate one. But maybe somebody replaced a second hand on a real Rolex. Or the other day at work I don't know what it was in before but there was a really pretty movement transparent back and they decided it was fake because of? Now I didn't think it was fake I took one look was beautifully manufactured but they had a reason What bothers me with counterfeit Rolex is or anything counterfeit watch related it is reminding me of a witchhunt. The early days of witch hunting how can we tell a which Manon which? That makes me wonder how many super fakes are really fake at all it's basically somebody deciding it's a fake based upon inappropriate assumptions. Like the secondhand is been changed or the watch was worked on the screws are perfect or other things. Other minor problems with super fakes for instance I have a long story the not going to tell the short version is I found the website once where they claim to be counterfeiting Rolex watches. They even had a picture to prove their counterfeit watch the problem with pictures online how do we know it's really a counterfeit watch and not a real Rolex watch that you're telling us is counterfeit. Oh and they had testimonials from all kinds of people who bought their watches and were very happy with the service of course the problem with the watch is you don't know what's inside it unless you take the back off and just because somebody shows a picture online and says this is their super fake maybe it really isn't a super fake they be there just trying to say that. We end up with a interesting problem of manufacturing a watch. Does Rolex actually make every single part found in their watch? Then the year 2004's basically irrelevant. This is because initially Rolex buys stock in the company and they manufacture Rolex watches. I'm assuming over time Rolex will acquire more stock and only in 2004 do they get the whole company. But the company itself hasn't really changed other than the name on the front of the building. The real question is did they really make every single component found in the Rolex watch from the beginning of time until end of the time? A lot of the components found in a watch would be extremely specialized did they make their own jewels or their own mainsprings for instance? But that is looking at the article they employ a heck of a lot of people now I would guess now that Rolex probably does make everything in-house. Especially when they have nifty CNC equipment like for making screws were he could make a huge batch of one type it instantly switch to another type where before he needed specialized machines for one machine for one screw now manufacturing all kinds of stuff in-house becomes very simple. But still is possible that in the early days they might have outsourced something may be perhaps. But conceivably we do have minor changes in thing is due to how things have been made over time which can lead to confusions over whether this is legit or not when it may be as a change of manufacturing methods oh and regarding the screws found in your Rolex watch? In about mid-80s I went to a school reunion in Switzerland. One of things we could do was visit a factory and I picked Rolex because I wanted to see the mass production making of Rolex watches. Which is very disappointed I did not get the sea at all because didn't see them making Rolex watches in their Geneva headquarters even though the building is really fake? So what did we get to see well after sales service because after all were watchmakers we should see that. Did learn something interesting about Rolex screws if your watch was sent to Rolex the screws that come back are not the ones that went there. As they are using powered screwdrivers they don't want to risk breaking heads off and they will replace the screws of every single watch. The other one of interest was suppose there's a scratch and you can see the brass? No problem they have a solution that basically electoral plates without electricity so the scratch goes away. The research Department was quite boring and didn't look like anyone was ever there. Then it was too long ago to remember all the details other than I was disappointed I want to see manufacturing.   Yes the joys of artificial intelligence that is more like a trained monkey that's there to please you.
