Hi Guys

I finally got time to start stripping down the 2824-2 movt and a small part, (according to ETA tech documents of 2016 ) went flying over and landed on the bench top.

I cannot tell from the specs exactly where it goes, number 43 key bolt?

Any help at all is appreciated
Regards

Was some time since i serviced a 2824-2 but have a 2836 on the bench. 

I think that is for holding the gear  or wheel on this plate? 9d8edee95cdda4f41dca9de22b01794b.png

Hi guys
Nope not the day wheel clip
Here are 3 pictures
And the ETA technical doc is an old one from2010 as compared to the 2016 I showed yesterday
This movt is newer in last 11 months

Still not familiar with that being part of a new 2824-2 movement.

 

Do you have a photo of your actual movement, specifically where this clip/spring should go?  Just watch to check the movement you have, where did you purchase it from?

Here's the part (2595/1) from a 2016 ETA2824-2, I believe this gear is factory fitted to the bridge from two adjoining parts/gears, no spring like you are looking for.

That is really odd. I have stripped several of these movements and that part looks totally unfamiliar.

Hi Guys
Yes I agree ,
The weird thing is the tech documents from ETA site is dated 2016.
It clearly shows the part as #43 - key bolt
and in the order of assembly for the wheel train it is last next to the dial support ring and date jumper maintaining plate.
I have scoured the web , no luck.
But go to ETA's site, its there.

If anyone has access, has an account there , is a trained in watch repair from being in watch apprentice can you send in a question about it? I wonder if Mark can.
Frustrating this is

I will ask again in case you missed it, can you post a photo of your movement please?  Specifically the area of the main plate where the part in question should be.

there is an ETA website out there somewhere that shows the actual disassembly of this movement piece by piece. i cannot find it right now. i've not seen that piece before, either.

If you're thinking of SwissLab then try here;

However, it doesn't cover 2824

I still believe that it should sit under the lower gear? Holding it together. But haven't got a movement that i can show it on?

I am not convinced what you have pictured is the "key-bolt" as pictured on the PDF from the ETA website, looking at the individual part pictures on the previous pages, part 43

    • 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  
    • I have acquired a Citizen Leopard 36000 watch. My reason for purchasing it was my desire to own a timepiece with a 36,000 BPH movement, and the price was reasonable. Another motivating factor was gaining hands-on experience with the mechanism. The watch is in good condition, but I intend to fully disassemble it for maintenance. First and foremost, if anyone has prior experience with this particular model, I would greatly appreciate their insights. I do not have access to Citizen’s specialized lubricants and will need to use the ones available to me, such as 9010, 8000, and 8300 grease. Additionally, I do not possess the appropriate oil for the pallet jewels and will only be able to clean them.
    • Hello all, I am working on an older Valjoux Chrono. It doesn't have a stamp on the movement anywhere but I believe it is a Valjoux 72. I installed the train of wheels and they will not turn. The problem appears to be the 4th wheel and the escape wheel are not interfacing correctly. I had to replace both of these parts as the pivots were broken on each. I sourced genuine Valjoux/ETA replacements. I think the problem is with the escape wheel as all the wheels turn perfectly if I remove just the escape wheel.  My question to those with more Valjoux experience is am I mistaken? Is this some other model altogether and I have the wrong part or parts?    
    • I would remove the wheels, check for damage and if not damaged, clean.
