The black hands with the lume plots are the original hands. I believe that Omega ran out of these black painted gold hands at some point, and now use the all black painted gold hands (with exposed base) for watches that originally came with the lumed gold hands.
I had a DD145.022 with those same fully painted hands as service replacements and the watch came with Bienne service paperwork stating they were replaced. They did not comment on not having the original type hands available, but that was my suspicion and I think by seeing your watch my hunch was correct.
Here's my old DD145.022 with the same hands (and a service bezel for the keen eyed).
