Your Walkthroughs and Techniques
Post descriptive walkthroughs of watches you have stripped down and serviced and/or repaired, parts you have made or techniques you wish to share.
This is an interesting section where we post our challenges and how we have over-come them. You can also post walkthroughs and share your techniques.
SECTION RULES
This section is strictly for those posting real step-by-step walkthroughs of actual repair or servicing techniques relating to watch repair and/or horology in general. The idea is that we help each other by describing or sharing our repair techniques, or telling a story of how we have progressed.
If you are not posting step-by-step walkthroughs, such as - you would just like to showcase a completed repair job, then please choose a more appropriate sub-forum for your content. If your post is not deemed to be a legitimate walkthrough then a moderator will move your post to the appropriate section without notice. Thank you for your co-operation.

Unfortunately I'm not that lucky. I started on the train side and after I noticed the binding I pulled everything out except the driving wheel to rule everything else out. It still binds. I'm going to double check that the pinion is fully seated on the staff first, then if no joy I'll push the bridge jewel up a fraction of a mm. Fingers crossed! -

Thank you for the advise!! It worked. The setting screw was a lock/unlock to remove the rotor. -
I have that French tech sheet too, it is a little different than the English one (eg, it doesn't have the auto works diagram). BTW, it looks like you are looking up the case number in the 1979 ABC supplement. The 1974 ABC catalog does have the 3093 case. As you determined it takes the 1222-5 crystal. When I serviced my President 'A' (which also takes that crystal), I was able to fit a 29.8 crystal from my DPA crystal assortment. Those are, in my opinion, a great deal. The assortment comes with 10 sizes each from 27.8mm to 32.4mm in 0.2 increments. I pretty much use them for any non-armored crystal that takes a high dome crystal. I think they no longer make them but Cousins has still has some in stock but when I bought them they were around $40 for the set and now they are around $100. Still, at 40 cents a crystal it's still a good deal. For the large driving wheel, I remember I once assembled the keyless/motion works first and when I placed the large driving wheel it was interfering with the setting wheel on the dial side as the teeth were not fully meshing and it wouldn't fully seat. If that isn't the issue I got nothing and am looking forward to see how you solve it 🙂 -
Not sure, but just looking at it, it seems like the screw on the right may be a fake? The one on the left may not be a screw in the regular sense at all, rather a 2 position device, I think you need to point the slot towards either of the 2 dots and one will secure and one will open. Like I said this is just my best guess looking at the pictures.
