UG Monodatic advice sought please

Hi, first post on this forum so please forgive ignorance!

I’ve recently come across a 1951 UG monodatic watch that belonged to my grandad. It was all but thrown away after a family funeral but my husband and I thought it was worth rescuing. My dad thinks it was purchased as new by grandad and it has been sat in a box since his death nearly 20 years ago.

Google keeps bringing me back here as a font of all UG knowledge....I’ve identified it as 1951-2 from the 7 digit serial number. The model number appears to be 40010 with possibly another 1 on the end (smoothed away) - which does not tie in with the UG info posted by Dre in the UG information thread.

The case has very faint writing around the edge, almost impossible to photograph, that says SHOCKPROOF WATERPROOF ANTIMAGNETIC and the another word I cannot make out - also smoothed away. I haven’t opened it.

It has the guilloche face in (what looks to me to be) great condition, raised coffin dial markers between numerals, gold plated, horn lugs. It does not have the roulette date wheel feature. Strap is godawful and irrelevant.



My husband took it to 3 watch specialists in Hatton Garden today (very mixed reactions) but none seemed to really know much about UG.

2 questions - any suggestions on where to get the mechanism checked, please, in London or Hertfordshire?

I can feel the bumper working and it keeps time but we have not opened it up. Secondly, any advice on where/how to sell it, or alternatively get a valuation? If we keep it, we should let the rest of the family know! Or we might sell it.

Many thanks for any advice.

Hi @susan792091 and welcome to the forum!

By far, heirloom watches are the best kind of watch, and yours is rather special as you can already tell from your research. Universal Geneve is perhaps best known for its iconic chronographs of the 1930s and 1940s, followed in the 1950s by the exquisite Polerouter family. But the Monodatic, produced in the early to mid-1950s, was right there alongside those models as seen in this catalog snip:

If you tilt your watch to the light, you might find a tiny UG shield embedded into the watch crystal. That's a sign that the watch has its original crystal, something prized by collectors.

If you decide to keep the watch, we recommend that you take the watch to a watchmaker who is familiar with vintage watches for a full maintenance service. We have a few UK-based watchmakers on this forum; try @ChrisN, at CJNWatch.co.uk. There are lots of tiny moving parts inside an automatic watch - a few of which move at 5 to 8 times a second - and these parts need to be carefully evaluated for past damage, cleaned and precisely lubricated, and then tuned and adjusted. Then you'll have a timepiece you can rely upon for many years.

Hi Susan,
that looks to be a nice UG monodatic 400101 from 1951-52 as you say. Gold plated case, dial looks in nice condition, should be a cal 138C, fairly standard bumper movement with date complication and sub seconds. I would think any competent vintage watchmaker should be able to service the movement. I'm not sure if the crown is original. Depending on the condition of the plating on the case, and after a servicing, I would guess the value between $750 USD on the lower end and $1500 USD on the upper end.
It's a pretty nice watch to keep in the family, most people do not end up with something so interesting, and given that it's not worth a great deal of $$, if it were me, I would keep it in the family.....

To the OP I can only commend you on the detailed research undertaken before even posting here. So many other enquiries land in this sub-forum with one blurry photograph and literally just "how much is this worth?".

I think the question of current value is covered above. One interesting fact about the Monodatic line is that it was marketed in the 50s as a premium reference in the product line up and could cost as much as some UG chronographs at the time. You have a lovely watch there.
