What movement in Regent super-automatic 25 jewels

[Cmmb8519]

Hi all

Would anyone know what movement is this?

I haven't disassembled it yet but the only mark I can see under the balance spring is "KI", maybe "CKI" (but the C is very fade and not sure part of the manufacture symbol).

Thanks!

Apologies, I was looking at the wrong place.
I can now see it is a Felsa 4033.
