Omega Automatic 1??????

Any additional images or information?

I have seen this case used on a couple of Omega prototypes and owned a couple of these cases NOS, I believe it was one that was ultimately adopted by Tissot. Its the 11000 case used on the Alaska prototypes but we aware this case was used for quite a few Lemania derivatives and also as I said I think the Tissot Navigator.

The dial looks like a standard 'brassed out' Big Blue dial, again it could be a proto dial but IMHO its not, I think it is a brassed out example based on the variation of tone across the dial and the lume plots look washed to me.



Hope this helps, its a quick dirty summary whilst in the office but any more info you can provide would help, any movement or case back images?

cheers Tom

Another bit of info

Some of these prototypes have come to market from the Alaska series in the last few years and despite being archived I know there were some real questions asked about more than a few. Don't forget that until a few years ago watchco had many of the alska spares (such as radial dials, star cases and other prototype chronograph dials) readily available for sale.

Maybe that explains the NOS NASA "find" in another thread.

These are according to JTT:


That would make it. 176.001. But hands are obviously different if yours is indeed a prototype. Nice one!
