I tend to agree with Paolo that it probably should have alpha hands. Given the replacement bezel and how white the hands are, it appears the baton hands fitted on yours are service replacements. If you haven't already looked, speedmaster101 has a lot of good info, http://speedmaster101.com/105-002/

You might try your luck finding trades or replacements over at omegaforums, a correct DO90 bezel was sold just today.
