Citizen gasket/seal question

[Davey57]

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

Lünette Dichtung translates as bezel seal so I would think that's what you need but I'm no expert!

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?
