Has this Automatic Geneve been redialed?

Hello fellow enthusiasts,

I was wondering if you could help me with this watch.
It is my first 70's Omega and it might be the decade but the dial looks so much better and more recent than my 60's and 50's Seamasters that it makes me wonder if we are dealing with a redial...
It's a caliber 1012, model-number is 166.0168.

Also, does anybody know how many colours came out on this specific model? I've seen a blue and red one, are there any more?

Yours sincerely,
de Gaulle

Looks original to me. I note that there is no T Swiss Made T" and am assuming this is a late 70's piece with non-tritium lume. There was ash grey dial as well amongst the more traditional and conservative offerings. Case is nice and sharp too.

Cheers

Desmond.

Original dial!
