It has been a while since i have posted here, but now i have a real specialty for You :)

Vostok Volna (wave) is added to the repairing/restoring queue. This special movement has a fine rate-regulator, indirect second AND indirect minute wheels!!! Moreover, the watch is not stopping if the second wheel is stuck into something. Other special features are the capped escape, second and 3rd wheels (at the dial side only the escape wheel is capped... lol)! The escape wheel is under the balance allowing a bigger balance wheel. 

The gear train was locking, hence the watch was not working. After closer inspection it turned out that most of the ratchet wheel teeth are gone... and the broken pieces were all over in the gear train stopping the movement. After removing the debris it started ticking again.

Nice movement.. I've got two of them somewhere. Only problem is the poor case and hands. The base metal case is really at odds with what I think is a fine movement. The hands on mine (both) are loose and go out of flat if jarred. Problem is its quite thin and using a stake etc doesn't work well here.

      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.
