Still no clear picture direct on to the face.
But from what I can see I think the dial is original.
However, the case has been heavily polished and lost any sign of the sharpness that should show.
The movement also looks a bit tired and has corrosion (movement tab, top left).
Compare it to this to see what the case/movement can be like for a good watch.

PS: Regarding T - SWISS MADE - T, may legitimate vintage Omegas have this marking which denotes that Tritium has been used as an illuminant on the hands and hour markers (thus two Ts).
The Omega symbol inside the Triangle is also quite normal.
