Citizen gasket/seal question


Question

I have come to a dead end while putting this watch together. I am missing whatever kind of seal it is that holds the crystal retaining bezel into the case. The watch was partly dismantled when I acquired it and some bits were missing. I have included some pictures which are easier to understand. 

This is the watch.

The bezel with crystal.

This is where it sits in the case. Not sure but I guess the seal or whatever sits in this groove. I don't know whether it might be a thin O' ring or a plastic shim. There is only about .5 mm for it to squeeze in. I wondered whether anyone has had a one of these apart before and know what holds it in. I am not too worried about it being totally waterproof so any suggestions would be welcome.

Thanks.

Thats great info thanks!  Could I ask how you found those parts and numbers?  I have tried inputting all the numbers from the case back into Cousins Citizen case parts search and it came back with no results. I only managed to find the stem and crown because I had a Citizen tech sheet with part numbers

 Interesting that the crown I found from Cousins had a different part number.  Just to be sure before I order one, the bezel gasket 393-7800 is for the crystal retainer and not the rotating bezel?   (if there is one)

Thanks again

I have been digging around and came across this. Someone has posted pictures of a strip down , 393-7800 looks like it is the one I am after, the black one in the picture is the crystal gasket for the the bezel.  I hope it's ok to post links to other sites like this, apologies if I'm in the wrong.  Anyone speak Dutch?

    • @Klassiker the AM220 is a good start, there's hints of this escape wheel cock and bridge shapes in the other larger AM movements on Ranfft as well
    • Not sure this will sent you in the right direction, but there is a chance 🙂 http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&&2uswk&AS_278 Something somewhat similar..
    • You did not tell what was that "extra" screw for. I would do the following: - release the mainspring - remove balance bridge - remove pallet fork - rotate train wheels manually to confirm they move freely. If they don't - find out why. Once that is resolved or confirmed, next stem - replace the pallet fork, wind the main spring just few rotations, push the pallet fork gently to see if mainspring energy is being transferred and wheels are moving - just take a closer look at both pivots of the balance staff. Again, gently and without pulling too hard - check both pivot, top and bottom. You may have bent one while removing the balance bridge several times (i hope you did not). - with the mainspring wound, replace the balance bridge. Often balance would self-adjust (impulse jewel / fork) and start moving. Gently replace the balance bridge screw. Good luck!  
    • Valjoux 23/72 ... hadn’t been worked on in a long time.  Tore it down, cleaned it, reassembled - everything worked ... until I realized I left out a screw. Tore it back down, installed everything fully this time.  Balance wouldn’t rotate.  Gears seemed like they were seized. Tore it back down, spent a LOT of time on each assembly step, ensuring everything spun freely.  Installed the palate fork - flicked back and forth as appropriate.  Installed balance as the last step.  No rotation.  Spins freely when “encouraged”, but it doesn’t continue. I pulled it out.  Confirmed that the hairspring isn’t kinked.  Jewels look fine (no cracks or chips).  I don’t have the means to check if the balance staff is bent, but the balance seems level and when I encourage some rotation, I don’t see any wobble. Any thoughts on what to check next? Thanks!
    • I installed the spring back inside the barrel yesterday and checked it this morning. The copper wire band is still holding. But now I have a new problem with this clock. The strike mainspring is going to break at the eye. Is it possible to cut off the end and cut a new eye or should the spring be replaced?
