Hi everyone newbie here. Has anyone ever seen an Omega Constellation like this? It has a 1330 movement. I'm trying to find out if it is a franken watch. The band is made in Mexico and it's genuine calf. The backing plate is 10 kt gold filled. Don't know if it works, It needs a battery. Is this watch worth repairing and cleaning if it doesn't work. Any suggestions where to send if it needs repair. The crown has a push button. Thank you.
