Since I have a restless brain I today decided it was time to practice on an ETA2824-2 Movement. 
I pulled the practice 2824-2 movements box out and blindly  picked a specimen. 

But soon I realized the pictures probably are so many it would be hard to upload.  So I made it to  a two part PDF series instead.

Excellent pdf’s and good timing, thank you as I’m currently working on one of these exact movements, and so far the amplitude is awful! Bit more work to do.

 

 

By the way - you have eight 2824-2 practice movements? How on earth did you manage to get eight?!!

Only eight! Then I must have misplaced a bunch of movements somewhere.

Like all scientists I suffer from a restless brain, this is nowadays confirmed by genetics. One of

the manifestations or symptoms is the urge to quite the voices in the head by manically investigate

a claim someone maid (ETA). In this case I probably had to see what really differs between the different ETA 2824-2 movement variants.
The conclusion was .. after some tweaking with the simpler model the biggest difference was mostly cosmetic.

It’s one of my absolute favourite movements. Simple, robust and with good enough precision.

Fascinating HSL!  That is a heck of a movement collection.  Have you looked at a Sellita SW200 and compared it to the ETA?

Isn't the 2824-2 basically an auto winding version of the 2801-2?  I believe all 2824-2's also have the stop lever for hacking, where it was optional on most variants of 2801-2?

Great pictures on your PDF's.  I have an infinite amount of respect for those of you with the talent to do such a great job of sharing such excellent how to's.

No I haven't any of the clones, just work with what I usually find in my watches. And investigate what the variations are within it's family.

If you take of the auto winding you would it should be a familiar sight except the train bridge looks som different, not sure if the 2801 has the stop lever. There will be some differences in the keyless too since this movement has a quick date setting. And if I don't remember wrong 2801-2 haven't got date  function.
If my distorted brain isn't to hazy I think the 2804-2 is the manual winding version of this one. But their all in the same family.

HSL i just want to thank you for this guide, being new to watch repair/service its become a very interesting and fun hobby. I bought a cheap clone 2824 movement and then found that a cheap watch i got off ebay also has an eta 2824-2 movement in it. This guide has been invaluable to me, again thank you for the time it took to post this.

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      By nevenbekriev · Posted

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.

      I did not. I thought about it, but I had cleaned it in my ultrasonic, and the tech sheet shows lubricating it in place already assembled, so I figured discretion was the better part of valor. Although since I have to depth the jewels anyway, maybe I pull the pinion off to rule it out 100% as part of the problem. Do you know if there's a safe way to do it? I don't want to use a puller because it would push down on the plane of the wheel, and that seems like a Bad Idea. I thought about using a roller table remover, but I don't think I have a hole stake pointy enough to push it down.
