Can someone help me identify this piece?

Hi there ,

This was my grandmother's, and I've inherited it.
Can anyone help me identify this model?
All I've been able to ascertain is that it's a Da Vinci moon phase pre-IWC.

any help would be appreciated.
kind regards,

Siham

Unfortunately not an IWC.

I concur. It's not an IWC. It is still a memory worth keeping.
