What is this part called ? Case ring ?

[Flubber]

My native language is not english so I don't know what to call certain parts. I'm trying to "fix" (in this case replace) an ETA quartz movement in one of my old watches. There was a nylon ring around the movement to keep it in place in the case and it was quite deformed and I thought I would order a new one but Ihave no luck when trying to find it on cousins and I guess it's because I don't know what to search for since it must be a standard part. Any help is appreciated.

I had trouble with that part also.  On one web site it was called a "movement holder" (which is confusing because that is what we usually call the *tool* we use to hold the movement). Other sites will call it a "spacer ring" or a "movement spacer", but I have also seen it called a "case ring" (often for pocket watch parts). 

I know Esslinger and Cousins UK should have them. Searching with one of the terms I mentioned should give you results.
