ETA 2782 Cross Threaded Screw


Recommended Posts

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

    • Haha. You're just in a wicked mood today John 😅
    • Heres my watch of today, a Smith 13'" RY . My missus bought me this for this Valentines day a bargain 14.99 with a reduction, the seller has occasional 20% off offers now and then so it was about 15ish with delivery. I love Smiths and i love bulleye dials, this is my first one. The watch arrived non working as stated and i knew what was inside and what would be against me, but i enjoy a challenge, we dont expect a lot if anything from pin pallet movements. A balance pivot was broken and i didnt have another staff but i did have another RY with a battered dial so i robbed the balance and tweaked it around to make it work apart from that mostly just a good clean and relubrication. Keyless works are pretty rough by design and the crown is a bugger to get in and out with the dial on, the setting lever hits the dial before it releases it, so a little mod is needed to help that along. Major problem was the pins on the lever were quite worn which make the old tg have a snow storm fit. Its a similar read for most pin pallets, these were brass as was the escape wheel. But perseverance is me, i didn't change the pins but i did spend some time dressing and polishing the worn areas which improved the trace a lot with some straightish lines 😅 and a beat error of .5 . Not sure what the lift angle should be on these and i Wasn't in the mood to work it out and who believes timegraphers anyway, but at the default 52° it runs with 260ish full 210 after 24 hours dial down , the verticals rates were pretty much all over place. So lets just put it in it's superlight aluminium case and see what happens. Been wearing it now for 3 weeks and it's consistently losing around 1.5  minutes a week winding each morning i think pretty good for an old pin pallet watch. I just love this dial, thanks wifey heres my Valentine's gift for yer sweetie x
    • I have a PDF below that will help. The problem was the PDF wasn't designed for this purpose it was designed to tell you what size watch you  have. Then it doesn't take into account movements come conceivably in different thicknesses.   watch-ligne-size-chart.pdf
    • That would be something! Which brings me back to;  
    • you think you're going to sleep tonight you're not, you're going to ponder the question of what makes you think those of the right parts?
