Something has probably moved in the keyless work . Usually is the setting lever that has jumped of the clutch wheel . you probably need to remove the hands and dial and maybe the date mechanism to fix that. Don't know how handy your are with tinker with watches. But sounds as it's a job for a watchmaker.

Thanks for everyone's help, especially oldhippy. I managed to get it all back together again. Manipulated the balance spring back into some kind of spring shape, and it's running very nice now. Most important, I learnt a lot for the next one.

I acquired an old ETA 2824 movement that was out of a Technos watch. While taking it apart for a thorough service I learned quite a bit about the movement. The keyless works, date change parts, sliding and winding pinions were different to the current ETA 2814-2. The stem was of the helicoidal type - but was missing. I was very lucky to source some. I also changed to rotor for a new Swiss one. I had great fun in stripping it down and, as this was my first ETA 2824 service, was amazed at the quality of the components. When I opened the barrel, the spring was almost mint condition, in fact, I think the movement had hardly been used. Now, after its service and bringing it back to life, I think it's a fantastic movement. Here are a couple photos and a video of the timegrapher readings. I think I could even improve the -/+ sec/day setting. Timegrapher readings for dial side up and crown down. There's not much fluctuation in other positions.

No broaches are five sided each side is a cutting face you insert and twist and the faces cut as you do so, they must be used at a perfect 90 degree angle to cut a perfectly centred hole, similar broaches are used in jewelling tools to enlarge jewel holes, the German ones that Cousins sell are cheaper than Bergeon and are very good the Indian ones I would give a wide berth.

All the teeth on that wheel look bad.

I will! I love crazy watch stories. J

Pick a spot where to start, the higest part, Take note of how and where the springs are attached, they should be open loop and attached to the pillars. When putting it back together make sure, the springs are attached to their arbors. So the movement is together and tightened down, wind the springs up and as you go you should be able to attach the open part of the spring over their proper pillars. You will just have move the parts into their holes. You can screw down the nuts a little by little, to hold things in place, not to tight or you could damage pivots.
