Universal Genève Four Digit References

First thing’s first. I recently acquired this special little cal. 262 and want to share it here. The serial dates this reference 7377 to around 1938. The glossy black and silver gilt dial is in flawless condition. In common with many dial designs from this period, the numeral font is another stunner.



The 34mm fancy case is unlike anything I have ever seen from Universal. The watch feels honest in hand and marked inside-and-out with the usual UG stamps one would expect to find. The case is mostly brush-finished but the faceted edges at 1.15, 4.45, 7.15 and 10.45 have a highly reflective mirror polish on them which adds real drama to the watch at wrist. The lugs are fixed and precisely follow the curve of the case.



Furthermore, the crystal attached to this piece is spectacular and possibly unique to this model. I have certainly never seen anything like it before with UG. It floats above the bezel and is clamped in place by the aforementioned mirrored frame notches.



The flat crown is a nice touch too and almost disappears from view when the watch is glimpsed head on.



I find the brief four-digit case number era at Universal Genève to be one of the most compelling and mysterious periods of the manufacture. Information out there is very scant (surprise, surprise).

Mr Sala’s book states that “It was only in 1936/37 that the reference number of the case was also punched alongside the serial number, initially inside the caseback then subsequently on the exterior of the case. From 1936/37 to around 1940, case reference numbers were four-digit numbers assigned at random and - by current standards - with no apparent logic. After approximately 1940, these reference numbers became five-digit numbers.”
As with everything UG from this decade, this broadly checks out in my experience, but not perfectly so. I have a 1940 Compax that indeed does follow the five-digit case numbering convention. However, I also own a time-only Colonial with a five digit case reference from early 1939, suggesting that the new system came in well before 1940 on some models. Maybe the time-only pieces, with a greater likelihood of receiving case updates and/or new styles, were the first to carry the five digit references as they were refreshed, ahead of the chronos? I guess we’ll never know for sure.

On his website, @mr.a places the four digit case reference era more like “mid 30s to approx 1938”;

I have to say that, as above, this timeline checks out more with what I have seen collecting UG. What’s a couple of years between friends? One final point here, stated by both Mr Sala and mr.a, is that the four digit case references, often starting with a ‘7’, were most likely assigned at random by the factory. For my part, I find this chaotic numbering practice so irregular. How strange to strive for complete technical accuracy and design precision and then just throw a random number on the finished product.

Please feel free to post any thoughts on this rather long opening post. Most importantly, please post any UG watches you have with four digit case reference numbers - all are welcome here!

Absolutely incredible. It's near impossible to follow that but for the record I'll add a couple of what I believe were 4 digit references that have passed through my hands.

I think this one meets the criteria as I believe the reference is 5631 with a 9 sub-reference. Numbers inside case back pictured below. The serial number puts it year or two earlier than yours. As noted by the watchmaker on the second photograph, this had a Cal 249 movement.

And here's a 5335 reference which is slightly earlier again. This time the third number (the 12) is after the serial. Is the third number a sub-reference or something else entirely like the month of production? A small gold ladies watch in the style of those retailed by Hermès with a Cal 241 movement.

And UG being UG also used this numbers for 3rd parties:

Jaeger 2609 with serial 617.413: https://www.phillips.com/detail/jaegerlecoultre/CH080217/177
Girard Perregaux 5965 with serial 619.223:

During the same period, late 30s, Zenith also used 4 digit ref numbers. At some point they changed their current number with another 4 digit number before going to the more common 5 digits. Interestingly, almost identical Universal Geneve and Zenith watches had very similar reference numbers starting with 20xx in 1936/37

I would love to find the Zenith equivalent. Amazing

I was the underbidder for this watch on Ebay, should you have been the one to beat me out. (This was some months ago). If you were, l would hope to get the dibs. 😉
