The reason the winding pinion is round is that the movement isn't winding the mainspring whilst doing other things on the watch like setting time, day and date. 
I took some minutes and tore down a movement to show what to look after and how to rebuild the keyless work.
The first picture shows the parts for you, to think about here is that the clutch goes in the right way, The straight cut gears should point towards the motion works, the winding pinion should have the angled gears towards the motion work too.
The clutch lever is placed into the grove in the clutch. If mounted as in the picture you should be okay.

In picture 2 the spring pops into place, just be sure it is installed correctly otherwise the winding action might feel a bit of.
Hope this helps....

On the ETA version which I am working on the winding pinion is rotating when you have the stem pushed into the inner position. Then it is winding your mainspring. Hence the name. I would be very surprised if it did not do that on the clone too. 

The only time the winding would not work is if you haven't enough force on the clutch to grip into the winding pinion. 
Of course a missing  crown wheel, broken click spring, and a broken mainspring would do it too but as I understand it you just removed the key less work to fix the release button issue.

The force to grip the pinion wheel comes from the spring in the part you marked 3 in your photo. The spring part has to be adjusted slightly into position after loosening it to get the spring action to the clutch lever.
It is what you see in my third picture.

Here is where the trick with the day/date happens. When you take it to the middle position you can see the small intermediate wheel jump into a other position, now you should be able to set the date since the wheel now is running the gear beside it. In the most outer position you can see the small wheel moved again and now you should be able to set the time.
 in the two latter positions the winding pinion stands still. You can see the gears in the picture above, I have taken away the bridge plate so one can see.

oops just realized I by mistake took an ETA2824-2 for the picture above.. well it's almost the same except it misses the gears for the day setting, winding the stem on yours clockwise should set the date and anti clockwise the day..

OK, so my problem is another story : )

At the moment I finished the work on my 2836, put the watch in the watch mover and let that make the work.

Anyway when I have time and open the movement again I´ll place that in the forum and I will work on the winding problem.

Thanks so far ; )

Even if the video is a little shaky one almost can see that the setting lever jumper (no:3 in your picture) isn't working as it should, it rises a little bit when going into winding position (Pos 1)
indicating there is something wrong there.
If you fix the spring action in this area, which probably got a little bit offset from the little to hard push on the setting lever (it holds the winding pin).
So dismantle everything again and carefully bend the setting lever jumper so it gets slightly nearer the main plate.
Make sure the grove in the winding pin is aligned with the little heel in the setting lever. 
Make sure the yoke is correctly placed in the clutch (sliding pinion) grove.
Make sure the setting lever jumper is correctly in position.
Make sure the spring on the setting lever jumper is pushing on the yoke.

I made a new video.... you still think its the setting lever jumper ?

From the video you can see the yoke isn't moving at all, this indicates it might have jumped out from the groove in the sliding pinion and that is why there is no spring action when you put it in the Winding position.

      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.

      Setting lever spring

      By Neverenoughwatches · Posted

      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.

      Yes, "Sold out" is difficult to understand. There doesn't seem to be a lot going on. It's been nine months since any new video was published on the Watch Repair Channel. The Level 4 course on watchfix.com has been in progress for what feels like forever (several years!?). Maybe Mark's enterprises aren't doing well or perhaps already so profitable there's nothing much to motivate him for more material. Or, perhaps these days he's more into crochet. The real reason is probably something entirely different but it would be nice/interesting to know. I don't mean to sound gloomy or pessimistic, but I wouldn't be surprised to be met by an HTTP 404. Every day feels like a gift. Speaking of watchfix.com I've been postponing the "Level 5: Servicing Chronograph Watches" course for a very, very long time. Anyway, I just enrolled on it so it's going to be very interesting to see the videos. I must say, IMO there's nothing really that can compete with Mark's courses when it comes to presentation and video quality. It's simply world-class and makes me associate with some really expensive BBC productions.
