ETA2824 setting issue

Hi all. I’ve stripped and cleaned a 2824 for the first time, all seems simple enough. Except! On reassembly of the movement including calendar side I found it really hard to turn the crown in P3 for setting the time. I’ve had it up and down several times today and can’t quite nail it. However, a likely symptom of this is that the wheel (minute wheel) circled in red below turns with difficulty one way, when turning the other though the central portion of it turns but not the main wheel.

Any ideas gang as I’m scratching my head here.

Thanks in advance ;o)

And here’s a closer pic of that wheel.

Did you put the little lever on the setting lever spring behind the setting lever. That is easy to forget the first time. The one that is shaped like a U . If that isn't on the setting lever it wont push on the clutch wheel. 


I think I did but I no doubt didn’t. Thanks Roger, I will check this out.

My bad . See now that it is a 2824. Not 2824-2. They don't look the same in the keyless work. So can't be that then. 

Maybe just a typo the movement in the picture looks more like an 2824-2...

One direction turns, the other dosn,t.

 The date is suppose to jump in one direction and not the other.

Check the date jumper at 9 hr (  a culprit, that is where I think the problem is) , the jumper is suppose to sit in between two teeth of date ring. Loosen the screw on date jump maintaining cover, that is the stuff at 9hr, a U spring pushes on the jumper.get the jumper in beteewn two teeth.

No, my bad as I didn’t realise they were different things. Apologies, I’m usually working on Seiko’s.
Here’s the movement ID at the start of the tear down and a pic of the keyless after rebuild...

As I understand it you had problems in the third position which sets the time. 
The tension to get a correct action is set by the spring rogart63 told you about earlier. If you haven't put the spring on the lever it will akt strange.

Quick date adjust should be in the middle position.
I attach a photo so you can check.

Thank you. I get the feeling from the suggestions that I have set the spring incorrectly. I’ll check this tomorrow and report back. Hope it’s this as it’s an easy fix!

The central portion is what should turn, if the whole wheel is turning then you have an issue. There should be a heavy oil at the intersection of the two parts.

All rebuilt and no better. This is with the keyless in P3 for setting. I turn the crown away from me then toward me and repeat this process. The video shows what is happening in the movement. Apologies for the shaky video, it was a bit awkward without an assistant!

You have the balance out yes? When you are turning backwards it's causing the escape wheel to run backwards, this is what's letting the large wheel move. It should remain stationary while the pinion slips.

Of course! Feels like that should have been obvious now you say it. Thanks you.

 

Did you lubricate the junction between the pinion and the wheel?

No... should it be just a touch of D5? Or HP1300? And I’m guessing that one should put a hint of oil in the friction point between the two elements?

      Is this a 'hack' ?

      By oldhippy · Posted

      These types of hairsprings become weak with age and very fragile. Which I expect it is that giving you trouble, and that wheel is not the correct one, if it were not bent I don't think the movement would run as the teeth are not the correct height. The problem you have is price which depends on you. It can be repaired but is it worth it to you, because there is little value in the clock. A wheel can be made and hairspring replaced. Or hang on to it and keep looking on ebay which is your best bet for replacement parts or even a complete movement but it will be like finding a needle in a haystack.

      Epilame / Fixodrop

      By Knebo · Posted

      I did that also for a few movements - well, mainly in/around the train jewels. I made big efforts to epilame the mainplate WITHOUT getting Epilame into the Pallet fork jewels (where it's not supposed to be, right?). I made litte barriers with Rodico around that jewel and used drops from a syringe to apply on the rest.  However, I've now stopped doing this. For three reasons: 1. It's a hassle and consumes more of this liquid gold. 2. I didn't see the need when using HP1000/HP1300 lubricants and grease for most part. The two places where I'd use 9010 (i.e. escape wheel and balance) receive Epilame in specific places... or the cap-jewel-setting of the balance suspends the oil sufficiently be capillary action (see my "conflict" about using Epilame on the balance jewels).  3. Lastly, and here I really wonder about yours and others' experiences: I felt that applying Epliame to the train jewels left them looking hazy (borderline dirty) compared to the (painstakingly achieved) sparkly clean results of my cleaning process. I just can't help but think that the Epilame residuals would mix with the oil and cause more friction/wear. I don't know.    simple: it'll stay there. It won't move any further. That's exactly what is happening if you epilame a cap stone. You end up placing the 9010 right on top of the epilame and the oil will sit nicely on that spot.

      Coil for old Seiko Credor -- 4002920

      By Neverenoughwatches · Posted

      There are some parts on Ebay for the seiko 6020A, it may just be a waiting game for someone to strip one down, NOS will be more scarce . K would strip your movement down to the module then start looking at other seiko movement to see if that coil is used, then seek out a seiko part dealer. Also Retrowatches youtube owner Mike may give you some advice try him on his site . He also hangs around amateur watchmaking groups.

      Setting lever spring

      By Waggy · Posted

      I would agree, in order to work harden something you need to exceed it's yield strength when it moves from the elastic zone to the plastic zone and you get permanent deformation and work hardening which is fairly close to its failure point, relatively speaking and dependent on the material/alloy of course. In theory you can load something constantly within its elastic range and not suffer work hardening issues.

      Probably easier to get a complete new movement - but CousinsUK list it as discontinued. Maybe someone on here knows a substitute movement ?
