I am sorry to not be in agreement, but stright sixes and nines, without the curly end, in the date/seconds/minutes subdials are not necessarly a sign of a reprinted dial. Even though definetively less common than the other font with the curly ending they do exist, and I have seen several examples, both live as well as in picture. Universal Geneve sourced dials from more than one producer and it is to be remembered that even though they are indeed beautiful dials, they did not have the strict controls and checks that, for examples, Pateks or AP or Vacheron had, especially because the Tri-Compax was such a large success that the volume of production was immediately very high and with that the quality (slightly) suffered sometimes. The only think that does not convince me in the dial of the opener is the font of Universal Geneve (or to be more specific the ratio between thickness of it and its dimensions) and the fact that it just looks way too new and crisp (always harder to judge a dial without a watch to compare the overall conditions). And also the absence of the dash between "Tri" and "Compax" (even though there are also very rare examples of dials with the word TRICOMPAX written all together, without dash or space at all).
But for example the dial lastly posted by rolokr in its 14k claw lugs Tri-Compax appears completly genuine to me.
