I’m betting original, but looking forward to hearing from the Zenith experts here.
Edit after reading the responses below: Another lesson in know your dial. I’m getting to know Omega dials, but Zeniths are still out of my league because I haven’t done my studying yet.
Seconds dial out of center as well as "swiss made"
Minute hand truncated and too long
BTW it is a two color and not a two tone
Good observation. Minute hand seems wrong. Doesn't mean that the dial is wrong though. I am not sure if I understand your point regarding the sseconds dial.
The spacing of the letters in Zenith. E in particular. One thing more and this is only my 1c worth but on the older models I’ve noticed a lot of the printed stars on the dial are not perfect like the example you showed and have a slightly heavier line weight. Not sure if that makes sense and it’s only an observation.
