I just have a very similar one in my collection. Not sure if it is really original from UG, but I think this regulator watches maybe have been build for UG from a third party. I just like wearing it a lot!
What makes me wonder is that dial of the ebay watch says 17jewels, but movement inside has only 15 jewels. And the printing of the hour subdial at 11 doesn´t fit. At least a reprinted dial imho. But as said before, not sure that these are origin UG watches at all...
