First the case: I've never seen a snap back case with an o-ring. As mentioned, the font and engravings look atypical. The pushers, especially, appear to be modern replacements to my eye (I believe that this one should have the
sharp edged mushroom pusher variant).
The Dial: I'm not putting money down on this until I see better pictures. But the things I don't like: signed "Swiss Made" at 6 O'Clock rather than "Swiss". On modern redials, this narrows the redial to one particular re-dialing shop in Europe, who has this habit.
In my experience, the "Swiss Made" is correct on watches that Universal made for third party brands (such as Girard-Perregaux, in particular), but not on Universal branded pieces.
The rounded "3" font in the hour counter subdial. If you get into the
really early Universals, this could be totally correct. But again, my thinking is that this model should have a flat topped "3". On modern redials, this again, narrows the redial to one particular re-dialing shop in Europe who has this habit.
I am not going so far as to call this an outright fake or certain redial. I'd like to see better pictures, and it may be from that early transitional period (discussed several times previously) at Universal where some of the usual tells were inconsistent or contradictory to later models. But I am highly skeptical.
