Looking for a suggestion on where to get 2 Omega parts

My watchmaker has my Seamaster on his bench. He originally was able to order the parts but now he needs updated training to obtain parts for coaxial movements. He said he could either send to Omega for service or I could wait a few months until he completes the training. I thought I would post here to see if anyone has any suggestions. If I can supply him the parts he can finish it quicker. If not then no big deal! I'll just wait it out.

These are the part numbers.
REF 7228605A33020 (date indicator driving wheel)
REF 7228500A9144A24 (date indicator white numbers on black background)

Cheers

I would probably wait for him to finish his training. Finding parts for the newer calibers won't be the easiest and I guess not the cheapest route.

But just for argument's sake, you can google search the provided references. The first one is for a caliber 8605 (with 8500 as a base) and the actual part number is 33020; you can search for "omega 8605 33020" or "omega 8500 33020". The other as "omega 8500 9144".
