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
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
