Hi,

I had to fix a hand and I obviously pushed the stem release button too deep : (

The stem doesn´t click in and I cannot change time, date and gmt anymore or wind it up.

I found some articles in the web talking about the keyless hacking problem.

 

Did someone manage to repair that problem ?

If yes, are there any good repair tutorials on the web.

 

Any help appreciated

 

Thanks 

Oliver

Don't feel bad, happens even on the Swiss made ones. It helps if you pull out the crown to the handsetting position before depressing the plunger. You need to use a screwdriver where the width is the same as the slot across the plunger.

When installing the crown/stem, press on the plunger and insert.

Like anvil says, should push with screwdriver width same as slot.

Refer to posting     Tudor/Eta 2750 stem    To see my drawings for safe stem removal.

As for now,  open the page  eternaltools.com , shows name and pic of parts.

1.lift the hour wheel

2 unscrew the minute train bridge ( one large scerw) and remove the minute train cover.

You can then remove the date  ring plate. Take extra care date ring bends easy.

Take pic at each stags of strip down helps the reinstallation.

Good luck pal.

Thanks for your help

Got it all going but when I deatched the big plate the small keyless part came with it, now I´m a bit 

struggling how to reassemble the movement. Is the position of 1 and 2 correct, maybe 2 holds the stem gear ?

Anyone did this job and knows what to care for?

Thanks

Thank you very much, that video worked out for me !! : )

I could finish the watch and it is working.

My only problem is the stem does not stay in the watch. 

Seems I distorted soome plates that hold the stem ; (

But for now I´m very confident.

kind regards

Oliver

Hi Jaycey,

I think that is my problem, In my case there is only a hole, so I pushed that pin out forever and that is why my stem doesn`t stay in the movement. Do you think that can be corrected, ie. I can get a spare part for the pin ? or is there a workaround ?

Thank you very much for your support

nice try, you probably damaged the releasebutton so it is now stuck and the release will not return to its original position.

Yes seems I pressed it through, as I can see through the hole : (

is this issue reparable or can I kick the movement in the garbage now ?

thanks

Oliver

Yes, it’s the part you are pressing on to remove the stem.

It should have 2 pins on one side, one larger than the other.
The larger pin is the stem release button. The smaller pin locates into the groove in the stem.
There is a third small pin on the other side that engages with the large plate (setting lever spring) this gives you the 3 setting positions, winding, date set & hand set.

Thanks, 

I could fix the lossen stem problem, the stem is hold by the keyless works no problem.

Position C ( time setting ) works quite good , date is changing as well and movement stops.

Postion B ( GMT & Date ) does not work

Position A ( winding ) does not work.

 

I got to find schematics or  learn to understand what happens in the several positions

 

Well its a hard way to perfection : )

After connecting the Yoke spring to the settings lever 

gmt/date / time setting work now like a charm.

 

only winding does not work or it is so subtle I don´t see and hear it.

I may have to buy a new winding pinion.

This never rotates with the stem, or maybe its on the backside of the movement ?

 

kind regards to all supporters

happy Oliver

Anyone knows a video where I can see what happens when a winding the movement through the winding pinion.

Does the winding pinion rotate in that position ( in my case it never rotates ? )

It worked when I first opened the movement but now I may have disconnected someting else on the backside of the movement ?

kind regards

Oliver

A square stem into the square hole of the winding pinion and the winding pinion does not rotate when the stem is wound means only one of two things.

Most probable; the square hole in the winding pinion is rounded off.
New winding pinion required.

Not probable; The stem is rounded off.
New stem required.

Thank you very much !!!

So the winding pinion does rotate when the stem/crown is in the 1st position full in ?

Thats what I expected,  I found one here but I can barely see that it has a square hole.

hmm the Winding pinion usually has a round hole but the clutch has a square..
The teeth of the cluch makes the Winding pinion rotate when they meet.

The clutch lever pushes the clutch towards the Winding pinion when the set lever is manipulated.
What you have in your link there is the Winding pinion I can be wrong..

      I looked at it like this, I've built a lot of stuff in my time, building structures and furniture,those are my creations and they will still be here way way after I'm gone. Traditional watchmakers felt the need to pass their knowledge on, ideas that they created . I assume with them as it is with me, leaving their mark on the earth, a way of being remembered. This creation of Mark's has brought thousands of people together to pass their knowledge around,  ideas that will continue to be used for lifetimes. Ideas that should continue to be procured. If for whatever reason the forum ceased to exist, not quite like Ranfft's, that didn't disappear but much less usable. Then that is sad, such a massive loss of communication between good people and a wealth of knowledge lost. There should be something in place for when that happens which could be next week, next year or in 10 years. Might not be a topical subject for a lot of folk or boardering on controversy, i did say i talk about stuff other people dont. But if you dont talk about it and something happens then you've lost it and you ain't gonna fix it .

      I've remained silent on this thread, and at the risk of upsetting everyone, the thing that worries me the most the the apparent absence of Mark. The moderators do a great job and the members also pitch in, and the site seems to run itself, but it is a concern for the future of this forum when the owner is absent for all intents and purposes. Like many of the comments above I would hate to log in one day and things be closed down as I rely on this site for ideas and knowledge and also cheer me up. maybe the Moderators could reach out to him, assuming he does not read this thread, and express our concerns and let us know the plans going forward? some kind of WRT ark

      That was the exact reason for me starting this thread watchie. Still we haven't worked out how the regulars are going to hook up if it goes tits up. I honestly think something should be arranged to stay in contact, we all help each other so much.

      Yeah ive watched that a few times before,  i couldnt find my old school dividers to scribe it up 😅 Yep thats the guy i bought a roll from . Thanks Nicklesilver that answers that perfectly and more or less what i thought an experiment over time would prove . The jumper arm is quite thick along its length, i left it that way intentionally, i thought the original was probably very thin, i didnt see that it was already missing. Setting isn't particularly stiff as such just positive, i still need to take it out and polish where it mates with the stem release.
