As others have already commented, the one on the left looks to be an all-original Ultraman (with a messed up bracelet with no end links and some lume missing from the dial, especially on the 1 o'clock marker).
The one on the right is a 90's Speedmaster that appears to have never been opened (red wax seal is still present).
If you are planning on keeping these as a family heirloom and want to service them locally in Nor. Cal, Worldtime in San Jose is the only place to go. Keep in mind servicing these will not be cheap (especially the one on the left). You'll probably have to spend a couple of grand between the two.

If you don't mind sending them out (not far, only to So. Cal.) LA Watchworks is the place to go. (Prices will be somewhat lower, job quality will be the same).

If you are planning to sell, best to just leave them as-is and let the buyer do whatever they choose.
You will need to get an Extract From The Archives from Omega (at least for the left one) in order to maximize its potential.
