Looking to source the correct crown for this 2998-1

I understand that both crowns pictured below would be correct for this reference. Am I right in thinking the NAIAD would be slightly more desirable?

 

Edit for photo of the watch

 

I don't know about the crown (my personal feeling of esthetics being that I prefer the A1 crown over the mercedes one)
But I wish you luck sourcing the correct bezel.
