I can't help with finding a watchmaker but some of our US members surely can.
If it was my watch I would:
Get the movement serviced.
Replace the crown with a correct item.
Have the case cleaned and some parts lightly polished, but not POLISHED.
Get the hour/minute/second hands replaced with the correct items.
Fit a new/correct Omega crystal.
Have the dial cleaned by an expert (lightly dusted, nothing else) and leave the lume plots as they are.
These models are becoming rarer by the day and any attempt to clean/re-lume the dial could end badly.
