Try to find the correct case and caliber

Good afternoon,
Anybody can help me to find the right case and caliber to this dial?

Hello!
I never seen before this dial, are you sure is it an original dial?

I’ve seen before a Longines dial with a similar pattern, except it did not have that aeroplane shaped pattern in the center. Unfortunately I’m not sure I have retained pictures of it. I believe it was a 1930s-1940s watch albeit with a very unusual style. Could you show the back of the dial?
Finding an exact match is a long shot unfortunately.
Dibs if you ever want to get rid of it though...
