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.

      Seiko 6139A & 6139B service manual WARNING !!

      By Endeavor · Posted

      The original 6139A manual is very clear in how to disassemble and how to assemble ...... step-by-step. However I haven't seen the 3169B manual, even in the Japanese version around, which clearly highlights the difference in center-wheel.   6139A Seiko Technical Guide.pdf 6139_A.pdf 6139A.pdf 6139b.pdf 6139B repair guide jp.pdf

      Which Watch Have You Got Coming In The Mail ? Show Us !!!

      Casio MDV106G-1AV Gold DURO200 I'm going on a long family vacation to Southeast Asia this summer and wanted a cheap but reliable beater in case I lose it, break it, or get robbed. Quartz movements aren't my thing, but I'm not dogmatic and this was a cheap option. A few years ago you could buy it for under $50, but since this particular model with the Marlin fish has been discontinued, you have to pay about double that, but I still thought it was acceptable. Sure, I could wear one of my cheap and very reliable Vostok Amphibian divers watches, but I have a personal relationship with them (having put a lot of work into them) and don't want to risk losing them. Strangely, I feel very excited. Maybe because I haven't bought a brand-new watch in over 10 years! 😀 The only downside is that this is the watch Bill Gates has been seen wearing, and I'm not exactly a fanboy of Bill Gates. Anyway, who cares!?

      Incabloc Lyre Spring & Low Earth Orbit

      This post has some pictures that describe how to get the spring back into the setting without having to disassemble anything.  With patience, this approach works.  The advice that the spring will ‘float’ back in when positioned just right is spot on. If you try to push it so it flexes and pops back into the setting, it’ll probably just fly away, as you’ve already found.  Hope that helps, Mark

      I recognize myself all too well. It takes a lot of experience and discipline to recognize when it's time to cancel and come back at a later time. Very well said! We should have a forum dedicated to this topic as it is critical to achieve success when working on watches. It's a lot more important than most other things related to watch repair. And yes, just a short break can make a world of difference!
