Hi Baron,
From Omega's own website (heritage section):
http://www.omegawatches.com/planet-omega/heritage/vintage-watches-database?ref=14292
and this great article by Bill, that you probably already know:
Funnily enough Mario Richon does not mention this important watch in his Omega Saga. But then it is not the only important omission of this otherwise excellent book.
Kind regards
PS. Please feel free to delete all my links if I have infringed this forums rule.
If I recall correctly it was strictly prohibited to place external links/ non original content on pspro, I cannot remember if this is still the case.
I just want to help without paraphrasing...
