Some of the most wanted references of UG are the 38mm waterproof (or pressure back or monoblocco) chronograph. Made in (very) limited numbers and not many survivors. The case is very similar to the famous Bovet/Vetta cases but they are certainly not the same. Unfortunately it is still unknown who produced this cases.

These watches were made in 8 references but I would not be surprised if a 9th one was made – reference 7076 – but so far I have not found a (trace of a)…

Bit out of my league so hope someone can help. Somebody offered me this Longines. Movement is a 15.26 with 5.6m serial. Diameter 37mm. Caseback is not marked Longines but that may be correct as far as I can see. Serial in caseback is same as on movement. According to the seller watch was serviced at the factory about a decade ago. Something was done with the hands. Dial was not touched. However: IMHO the logo seems correct but I assume the dial is at least relumed. Curious about your…

Sometimes I run into interesting stuff. Recenty this UG was posted on IG:

I always check the serials of watches like this against my mastertable of chronographs to see whether they fit in (actually: fit out) and this time it was a close call with a Zenith serial. This watch was sold in the past by L'Orologiese but no working links anymore unfortunately. Serial of the UG: 596.534, Zenith: 596.547. However: these numbers were not the only ones in the caseback. Both watches…

Interesting to see this nice snail dial just sold for USD 78.125 incl. fee. Link: click. I know specifics of 51 examples but have only 1 other snail dial on record, which sold for EUR 156k in 2019 (see: click). Cleaner dial but replaced minute hand and not matching (also perhaps relumed as well and what about the right index print…)! Of the 51 I know at least 6 are not matching (but 1 could potentially be rematched) and even the one in the Longines museum is not(!) so this is a…

Couple of weeks ago I bid on a book set. Auction house from Poland. I had to submit a KYC form before I could bid anyway, which was already annoying. Estimate was EUR 3-5k but estimates are useless anyway. So guess what my bid was (and if you any doubt on auctioneers knowing what your bid is this is your proof…)

Another remarkable one was this: https://www.reuters.com/world/europ…etrieved-italy-after-canada-theft-2024-09-19/
