My uncle said he bought it in 1960's. He was its first owner. Over these several decades he just occasionally put it on because this Omega was too dressy for his job. (He was a bus driver before his retirement last year.)
He asked me if I know how much this watch is worth in the second-hand market. I said I didn't know. But I made it clear to him that, if he really wants to sell it, sell it to me.
