Dear fellow Omega - purists,
After having contacted him following a post on his friend building up an extensive (to say the least) Omega collection, Ruckdee advised me to post on this forum regarding a specific question for which I have not found, so far, any clear answer. It could be that some of you might help in the quest of the truth, and I would be grateful in advance for any information I could gather.
Some years ago, I found on a flea market a nice seamaster chrono. I was attracted by its shape, its dial, its overall condition and by what I believed was a reasonnable price :




Back home, I tried to gather some information on the model, and in particular on the reference engraved, 176.001 :

This exercise has definitely brought some confusion in my mind, since information is unclear about this model. What seems to be more or less clear is that :
- Ref 176.001 and 176.007 are very similar
- Ref 176.001 and 176.0001 are identical
- Ref 176.001 has been replaced by 176.007 (or 176.0007) in 1972 (as shown on the information notice from Omega):

- Some casebacks of ref 176.007 are engraved with both reference 176.007 and 176.001, the latter being crossed, which confirms the previous observation
What is still unclear regards :
- Are 176.001 and 176.007 cases absolutely similar ?
- Is ref 176.001 a prototype that was never produced, but immediately replaced by 176.007 ?
- Re. bezel : inner bezel (with tachymeter scale) could not fit on my watch, but has an external bezel ever existed for this ref ?
I have to admit that I gave up couple of years ago, but the post of Ruckdee revigorated my interest for this mysterious reference. I would therefore be very glad if any of you could post pictures of other examples of ref 176.001, or what is believed to be so, so that I could get closer to some certainties...
Thanks in advance for your help. This is my first post on the Omega Purists forum (I am more JLC-oriented), and hope I did not breach any unofficial rule here. Furthermore, some of you may have intervened on other fora some years ago, when I first tried to understand all this; they could here pursue their reflexions...
Best regards to all of you,
Karmin
