··not the sharpest pencil in the ΩF drawerIntruiging. 2052 may be the predecessor of 5002.
I respectfully disagree.
In this same thread we have a pic of an old catalogue, with a 7066 reference and a "Compur" dial.
Moreover, from what I can see, again in this thread we have examples of Compur models with 750k serial.
I can't proof anything but to me these are swapped dials. This case was an early waterproof one, and it's normal for me to think that most of these dials were damaged at some point and swapped with Uni-Compax dials.
But yes, I see there are many examples that you showed us. So I guess I'm in minority here 😀
So I definitely don’t see any problem in having the same ref. as both Compur (30) and Uni-Compax (best example being the 22409 Spillmann).
Very interesting ref 5923 with batch number 68 Sold for cheap: https://www.ricardo.ch/de/a/universal-geneve-chronograph-18k-vintage-1237577422/
Nice 5166 although I have my doubts about the dial (swiss made?) https://www.chrono24.nl/universalge...r-30-unver-285-rare-bi-compax--id29952034.htm
