I found two sets on line. One much cheaper than the other.
The cheapie:

You need to measure these to see if they will fit and have a watchmaker who can re-lume them to match each other.
More expensive:

On these, you need to contact the seller. The description say they they
do not fit Cal. 30T2 SC, which is what I think you have. He is a vintage Omega expert and watchmaker and may be able to help you source the exact right part.
Good luck,
