Universal Geneve Compur 5150

Rare bird. I don't think there is a relation between the bezel and the Roman numeral. Dial in itself looks legit

I've seen more around these serials.

Great vintage Chronograph. Just perfect. Congrats.

I've had a few Compur from around this time period, although both serials are a bit earlier (629XXX and 645XXX) than yours and the dial style is completely different, so not much help. I'll include the white one below.
I'm assuming this pic from ebay below is your same watch? Zoomed in close there's some things on the dial that seem odd. I'm not saying it's a redial, I'm just saying I've been staring at it for a long time now, and I'm not completely settled.

Spacing/detail of outer dial is problematic but overall, as I said, the look is great. You will need to learn to love and live with ambiguity on this one.

I guess Matt is taking a more blunt approach than me 😆
It's the kind of dial that looks fine from a distance and at first glance, like in the first photo you posted. But if you dig into the details, everything just starts looking wrong the more you look at it.
The UG and Compur text if you zoom in, not good.
The subdial fonts, not good.
The running seconds subdial centering is quite off.
The outer track is wonky.
The word that Matt used and I think best overall describes this dial is ................"shaky".
Original dial print should be crisp and precise.
However this could be the kind of dial people may argue about, and if you go back to the seller he may completely dismiss the so called forum "experts", etc and insist the dial is original.
What I will say, it's always more difficult to evaluate a dial by itself, it's much easier to make direct comparisons. So the best possible research you can do if you want to investigate further is ideally find this exact dial elsewhere, or at least very similar dial from this time period. If you cannot find such a dial, that also tells you something. (Some may say the print quality on this example does not even justify or necessitate further research, but I'm just talking generally).
I had a look through Sala and could not find anything useful.
In reviewing everything that has passed through my hands, the closest I could find was this roman compur 30, however it is later serial (728XXX) and different dial style, so not much help. But it is an example of overall crispness and print quality from an original dial, for comparison.
I would be confident to say your example is an older redial, and if anyone insists otherwise, my response would be, show me another same or similar dial for comparison. IMO discussions centered around reviewing actual examples are more useful than exchanging opinions.

redials were normally done on the existing dial, not blanks. The dial needs to be the exact size and shape and the dial feet need to be in the exact position, so probably easier to just redo the dial that you know will fit rather than starting fresh. Dial would have been stripped and reprinted. Was very common service, and no one was concerned about originality back in the day.
