Why are the minute indexes and minute track so inconsistent?
Is this a “feature” of this particular ref?
I would otherwise written it off as a redial.

 

Totally original to me.
Here is another example on chrono24

https://www.chrono24.fr/universalge...versized-vintage-mint-like-new--id2834957.htm

 

The eBay example is stunning, looks really unpolished and with the original band. Shouldn't last long!

 

I stand by my statement. There is something uneven on the Argentinian one.
The number of visible minute dots are uneven on either side of the minute indexes. Have a better look. UG was known for their attention to detail.
They would never let that pass.

 

Right. But I can’t believe the whole dial is a redial. All fonts looks really great!

 

I suspect the indexes have been removed and dial cleaned, before being reassembled. Or something similar
IMO there have been work done to it one way or another.

 

That’s sound good to explain this little issue

 

I know. Sick, but it would’ve haunted the living daylights out of my collectors soul.
Little it may be, but for a watch in that price range it would have put me off.
Who knows what other trickery they have been up to?!

 

Finally had time to attempt to research this and although I own three pretty nice Uni Compax, I'm struck by the thin coverage in Sala (Reference Photos) First example looks odd and the second looks perfect.

 

I'm so habituated to ignore these pieces from Argentina that I didn't even look twice when I saw it on eBay. If one of them was legit, someone could probably get a good deal on it.

 

...But this is the case with the one @Florent links to as well - why isn't that a problem there?

 

Entirely genuine to me although I cannot explain the minute track and markers anomaly.

I have a watch with almost identical dial and hands. The serial numbers of the the eBay version, the Chrono24 version and my watch are all within 500 of each other. The case reference of my watch is 32601-1. The case reference of the 18K versions is 12602-2.

My dial does not have the issue with the minute track.

 

Seeing your point!
First of all not a head on picture on Chrono24, so harder to distinguish, especially as I only had an iPhone to view.
However the Argentinian one still seem more inconsistent IMO.... The chrono 24 seems to have 3 small minute markers on either sides of the index, relatively consistently. Where the Argentinian one seems to be random 2 one side, 3 the other side.

There are some subtile differences between the last steel cased one and the gold ones above.
Actually not the same dials. The minute track on the steel cased one is narrower. Swiss is printed below the 6 o´clock index, opposed to above, and sub dials almost extends to the lume plots as a result of the more narrow circle.

 

Well, inconsistencies are just that - inconsistent. Anyway, I'll bow out of the discussion as UG aren't my field (what is..??), just thought I'd comment on that little point. Wouldn't mind either watch in my collection

 

What does the very knowledgeable OP think?

 

I recently purchased a UG uni-compax 124146 3.
I have done a bit of research prior to biting the bullet and my conclusion is that there are many variances of the same model, especially when it comes to the dials.
I personally can't say if this dial has been tempered with in any way. The case looks unpolished, just like mine. According to the serial the watch is from the early 60s, which is the last decade when these UG references came out. Maybe it has been preserved very well by someone rather careful.

 

pic?

 

This is ref 124146 3. Yes, they did have an extra digit sometimes to mark certain variations of the model.
