The UG Aero & Dato Compax thread

This - very rare - black dialled ref 22430 (so 37mm) was auctioned today for GBP 3.200 excl 27% fee: https://www.easyliveauction.com/cat...ques-collectables-auction-day-one-1--lot-188/

Will need some work - the corrector pusher is a replacement + crown + seconds hand. But surely will be a cool (and mega rare) watch.
Anyway, this is the second black dial Dato-Compax that I have ever seen.

Btw. Do you think the lume on hands is original!?
I have been asking myself this question for a long time - on many black dial UGs the radium hands are greenish. Is it possible that it aged differently than on white dials? Or are they just all relumed?
Does anyone know, what the color of the lume was when it was fresh? Zinc sulphide (used for lume) + radium is a warm whitish colored powder, turning yellow/brown seems more logical than turning green…

Mhm, so if I understand correctly, if it had the metric system it wouldn't have anything written like "distance" or sth. That spot would simply be "empty"

The metric system ones usually have “BASE 1000” written there instead.
(On later dials it’s sometimes just empty for the metric ones - like this 22290 here: https://omegaforums.net/threads/universal-geneve-aero-compax-22290.113809/ )

What do you guys think of this one? Dial looks too clean, but maybe is a very good redial.

How do you know? Because it is very clean, or is there something in particular that gives it away?

This specific design was never made by UG

The first, and easiest tell is it doesn't save Aero Compax over the chrono minute sub counter. Also, I don't recall seeling one with two different color printing on the dial. Also the outer scale just looks incorrect.
