The date is correct, but this one is not on my wrist, today. This one spent about 50 years, slumbering in a lozenge tin of Omega bumper parts, all dismantled. Then I discovered the dial in that same tin! Everything was there, with evidence of rust on a few parts, but no case! I resurrected it. I posted it in the message board, mentioning I didn鈥檛 have a case. Several months later,
@Tritium , a collector from Madrid PMed me that he had an extra NOS steel case! Voila! Here is the result.
