Nice! I just ordered the exact same one from Andrew Got my tracking number the other day. I am expecting it to arrive sometime next week. I can’t wait! Jim

I have used Gorilla Glue and it holds up awesome. Like someone already mentioned, it does expand. The trick is to use a very thin layer of it. What I do is put some on a piece of cardboard, then take a pin and dip it into the glue on the cardboard. Then I make about 12 little dots of glue on the bezel groove where the insert sits. It does not look like alot of glue when you are done, but don't worry,its plenty to hold. And the best part is that it does not set up for about 15 minutes, so you have plenty of time to make adjustments. Jim

Excellent repair! Thanks for sharing.

Hmmm, not really. The click that I am hearing is crown wheel, 420 snapping back towards the ratchet wheel, 415. I think we both maybe using different terminology, and that is what is confusing both of this. Let me try it this way: In the above pic, gear "A" is the one that I am seeing move. When the rotor spins, gear "A" moves in the direction of the green arrow. After about 2 turns of the rotor, gear "A" then snaps back toward gear "B". I think this is happening because when the rotor moves, it spins gear "B". Gear "B" can't move as it is engaged with gear "A", and gear "A" can't move because the click has it locked. So when "B" spins and "A" is locked by the click, "B" appears to be pushing "A" in the direction of the green arrow. The 2 gears then get to a point where the teeth are no longer meshed, but rather tip to tip. Then "B" moves just a little more (because of the rotor) and then the teeth of the 2 gears are in a position to mesh together again, so "A" snaps back towards it. My guess is that it is the click spring is what pushes "A" back towards "B" when the teeth line up again. At no time does "A" spin. It just moves in the direction of the green arrow. It is quite possible that this is perfectly normal. Every thing that I can see points to this being how the movement was designed to work. It just seems odd to me to have 2 gears slamming into each other all the time. That is why I am trying to find out if indeed the movement is supposed to work like this, or if I have a problem that needs to be addressed. I hope that explanation was a little more clear on what I am seeing. If not, please let me know and I will try to explain it better. Thanks! Jim

Ouch! Sorry to hear that. But it sounds like you may have a different problem then I. EDIT: I just read your thread and saw the gear. I have a sneaking suspicion that mine will be doing that same thing. Bazz was kind enough to test out his 2824-2 the same way I did mine. He said that his crown wheel also snaps back toward the ratchet wheel like mine. I have a feeling that all 2824’s do it. That being said, you have 2 gears that are constantly snapping against each other. It’s just a matter of time before the teeth start breaking. How old is that movement?

Marrick, Thank you very much for the info. I think I may have confused myself though. The gear that I have circled in the actual color picture (first post) is the gear that is snapping. It is also the same gear that is labeled as number 420 in the drawn diagram ( I now see that other little black gear that you are referring to). According to the tech sheet on the ETA 2824-2, number 420 is the crown wheel, and 415 is the ratchet wheel. I suppose it is possible that the tech sheet is mislabeled however. The issue that I have is not with the meshing of those 2 perpendicular gears. It seems to be with the meshing of gear 420 and 415. When I hand wind, every thing is nice and smooth. It’s when the rotor is turned that 420 snaps. Perhaps you can PM me your e-mail address, and I can send you the video that way. To be honest, I am not even sure that I have a problem. It is quite possible that all 2824’s do the same thing that mine is doing. I am just trying to get someone with that same movement to do the same “test” as in the video and see if they get the same results. If they do, then I am good. If they don’t, then I know I need to find a watchmaker! Jim

I agree Usil. I appears that the design allows for the crown wheel to move around. What I need to know now, is if the crown wheel is supposed to "snap" towards the ratchet wheel when the rotor is turned.

Ok, so after searching the internet for a couple of hours, I finally found an exploded view of the 2824-2. Turns out the gear I am questioning is the crown wheel (420 on the diagram). It looks like there is no bushing for it. The center hole for the crown wheel is over sized, and the crown wheel screw has a large washer to hold the crown wheel in place. From what I can see, it is designed that the crown wheel is supposed to have some “slop” in it to move back and forth. Am I seeing that correctly? I also see a “U” shaped spring (430 on the diagram) called the click spring. Number 425 on the diagram is the click. Does the click spring control the movement of the click, or the crown wheel? If it controls the crown wheel, then maybe I have a broken click spring? Thoughts? Jim

All I really need is for someone out there with a 2824-2 to do the same "test" with theirs like in my little video, to see if that gear does the same thing. If it does, then I know it is normal. If it does not, then I know I have a problem. Any takers? Thanks, Jim

Ok, thanks though. I know there has to be someone out there that has a 2824-2 that can do the same test to it to see if theirs does it as well! Jim

Here is a video of what I am talking about (PLEASE RIGHT CLICK AND SAVE TARGET AS to save my bandwidth) http://www.cardboardrobot.net/ecb/MVI_0037.avi Hopefully you can see what I am refering to (video is not very clear). Jim

I had the same issue with mine. I was 2 seconds away from cutting the spring when I decided to try different positions of the bezel. What I mean is, there are 12 sharp edges. So I just tried each one of the 12 until I found one that lined up perfectly with the 12 o'clock marker. Then I just slapped the bezel insert in. May not work for everyones, but it worked for me and is worth a try before you start cutting the spring. Jim

Hello all, I have an SMP with an ETA 2824-2. Today I noticed an odd sound during winding (not manually). I was using the automatic movement to wind the watch, making like a swirling motion when I noticed a “click” that was very repetitive. For every 4 turns of my “swirling” motion, I would here one click. I took the case back off, and proceeded to watch the movement very closely while turning the rotor by finger to see what the clicking was. What I discovered was the gear that engages the manual winding system (forgive my lack of proper watch part terminology) was “rearing” back and then snapping forward. The gear I am talking about is this one: Is it supposed to do that during winding with the rotor? When I pull the crown out to the winding position, and then turn the crown in the direction you would to wind, the gear moves forward (or up, depending on your view) to engage the other gears as it should. Then I turn the crown slightly counter clockwise, then the gear then retracts. But even after using the crown to retract it, if I spin the rotor, I see the gear rear back and snap forward again. It’s almost as if the gear is not fully disengaging from the rest of the winding movement. Is that normal for the 2824-2? Or do I have an issue that needs to be looked at? Thanks in advance for any input. Jim
