Naiad Crown : really produced by omega ? or not ?

Hello

I have heard several different information about the NAIAD crown .
"This is not a real omega part , this is only for service , sold only after repair of the watch .......etc."

I am a little bit lost.

Do you know if this NAIAD crown is at least a fake , or was this crown was really produced and assembled
with the new watches

and for what purpose ?

Thanks in advance for your opinion
