Based on this image from the UG archives, it seems that there was a Big Eye reference before the 884100.

As far as I'm aware, the watches in these records (the 'résumé du production') were all actually in production but if it were, it seems surprising that one has not come to market.

Does anyone know what 'SOC' might be an abbreviation for, as that might answer the question?

22901 is not included in the list of 'old references' that changed on 31 Dec 1964 and neither is the 884100 in the list of 'new references', which suggests that the 22901 was not in production on that date.

Apologies for the quality of the image; my focus was elsewhere at the time.

The crown looks thinner than normal and the hour and minute hands are different than normal (which normally have very thin lume window)

Nice work, thanks! Concerning the movement, I have seen at least 3-4 examples with a cal 84 inside (instead of 125).

Hard to believe the infrequency of “Big Eye” Uni-Compax pics/posts/threads here on OF over the years. Pretty much just this one above, and one brief thread from 2018 as far as I can tell. I presume this is largely a function of how few examples seem to be known in circulation. So consider this a much needed personal “bump” of a wild and cool reference, 884100 / 02. Just acquired mine in recent days, and couldn’t be happier with it!

If you’ve got em, share em! (Regardless of black /01 or white dial /02 version!)

I am desperately in need of a signed crown for my UG Big Eye. Would someone who has one please post the diameter and thickness. If anyone has one for sale that would be even better and I would certainly be interested.

You also need to know the tap size.

Those blued hands are crazy! So cool!
