My first disassembly and as luck would have it, I think I have a cross threaded screw. I believe this is a setting lever screw. I noticed when putting the driver blade to the screw head it was in rough shape and I can't get my driver to take to the screw slot. It just slips out without the screw turning at all. Even if I could get my driver blade to stay on the head, I'm afraid to increase the pressure here and afraid this may be a steep learning curve. Any advise would be greatly appreciated.

If the setting lever's still functional then why do you need to remove the screw?

Then I really need to look at the picture more carefully and you need the study your terminology better?

I'm attaching a PDF of your parts lists. So you get the names right and a picture With some part circled.

The image you have is pointing to a post which does not unscrew it's usually machined in the plate. The part that is riding on the post according the parts list is called a Yoke. The setting lever in This watch has already been removed and it looks like it's one that doesn't have a screw. So basically you should build just pull this off the post unless it's stuck on with rust or dirty oil or something then you might have to move it back and forth a little bit but it should come free as there's no screw holding it in place.

Its fairly cheap to live here, medical bills are non existant if you are prepared to wait to have anything treated. But that is slowly changing and we may not have that for too much longer. My policy is look after yourself and just dont get ill !     And houseing area taxes arnt too bad either.

It doesn't look like a properly formed screw head and yes it's usually a post, so hopefully it will slide off with a little effort.

I dont think that is a screw there matey. Setting lever screws are quite often on the other side on vintage swiss. What movement do you have there. Not set lever probably  yoke. Where are the rest of the keyless

Many thanks to all of you. Apologies for the wrong terminology JohnR725. I did acquire the same document you sent me (Thank you very much) before I read your reply and I did learn, the yoke is indeed what I should have referred it to. You were both correct as this piece is held only by a post and not a screw. In my defense I think someone before me was making the same error as the top of the post is quite messed up, but admittedly, my photography does not show this very well, and my magnification probably did me no favors. I appreciate everyone's patience here in helping me on this learning journey.

The yoke does move freely but because the head of the post is somewhat mushroomed, I will not be removing it. 

Cheers

      Seiko 6309 intermittent stopping of the seconds hand at the same positions

      By Disgrace · Posted

      Hello everybody, sorry for the late reply. Thank you all so much for your help and your tips. I got lucky and found a replacement wheel bridge for cheap which actually ended up being in decent condition. I decided not to do anything about the mainspring barrel pivot since I didn't have the right tools and the barrel didn't have much endshake anyhow. I am happy to report that the watch now runs great, I have regulated it to about +-10/s day which is fine by my standards. The timegrapher result looks decent as well, although beat error is around 0.6ms which could be better I suppose. Amplitude reaches over 230 quite consistently which I'm happy with also. My lighter fluid has also been replaced by balance spring cleaning solution and now the springs don't stick to themselves anymore - who would have thought. I'm super happy with this watch, it might not be worth a whole lot but it's awesome that I could restore it and it makes me wear it with pride. To me it's a genuinely good lucking watch, it'll be my daily driver for a while. Thanks again to everybody for their input! I couldn't have done the repair without your help.   Here are some images for those interested, the bracelet isn't original but I don't really mind:

      Is this a 'hack' ?

      By nevenbekriev · Posted

      Balance-hairspring system is oscillator with big Q-factor. When all in the movement is OK, the rate (frequency) is verry close to the own resonant frequency of the balance-hairspring. But in some cases, the movement (with foult) will force the resonator to work on pritty different frequency, sometimes faster, and sometimes slower. When this happens, the amplitude is always weak. So, the first thing to ask is what is the amplitude. If it is more than 180 and the hairspring doesn't touch itself and anything else, then for sure it is 'short'. If the amplitude is weak, then the first thing to do is to understand why and rectify the problem. At this time no point to check timekeeping. But, if one doubts that the hairspring is not correct, then He needs to calcullate the rate of the movement, then to 'vibrate' the balance-hairspring out of the movement and to measure the free oscillations frequency (period) with timer in order to ensure that they comply with the rate. If we have pictures, then it will be easier to tell something about that wheel.

      Landeron 248 setting eccentric studs

      By Klassiker · Posted

      So much work has gone into this! Thanks again @Jon. I will go back and check my adjustments from last weekend. A few questions for you, if you don't mind. In the reset position, I can understand the problem if the gap between the hammer and the minute counter heart is too big (slide 77) but what is bad about both hammers being in contact with the cams (slide 76)? I read somewhere that Landeron recommended grease on the runner cam, but the minute counter heart should be dry. Is that so, and why? How many tads in a ligne?

      Could you glue two pieces together for rigidity and separate after forming?
