IWC Ingenieur Automatic Laureus

Hi all
First of all I beg you to excuse my poor english,, I'm french.
The fact is I'm considering to buy an Ingenieur Automatic Laureus, but I would like to know if the caliber is an ETA or a Sellita. It seems ETA are 30xxx references, and Sellita 35xxx. And it seems the Laureus Ingenieur has an 30110 caliber, so it should be ETA.
So ETA or Sellita base movement?
Thanks

It's based on IWC's specifications for an ETA calibre 2892.

Thank you
