in the 3000
formed the basis for the ETA 2892. The date version was the 1466
This one is probably a 1455 or 1456(no date, same family as 1466), although he has the rotor covering it.
These movements were the last ones Eterna made in house before
ordering special versions from ETA for their watches I
believe.
I own 3 Eterna-matics but this one is my favorite
