Help Identify My Ladies Omega Watch I just Brought

Hi everyone, I just brought this and all I know is it was sold in France and has a gold plated case and chain, but a hallmark on the clasp, so this must be solid 9ct gold. Watch actually goes and keeps time.

Face reads:
OMEGA
FAB SUISSE

Clasp reads: 9C

Inside Case reads;
Omega Watch Co.
Plaque or L80 Microns
Central Watch Case Co.
C.B 2443-9

There is also a series of numbers lightly scratched onto the inside of the case; 3821, 44886, 41734, J, AK6848, 306087, 9855A1

Yes, lightly scratched onto the inside of the case: 3821, 44886, 41734, J, AK6848, 306087, 9855A1

Thanks for the help. I found a good listing on another 2443-9 price 400Kr. It's a post WW2 watch: https://www.kaplans.se/en/auktioner/3157/vara/1288480
