Help- referrals for a watchmaker in Orange County, Ca.

I have a 1967 Omega Seamaster 300 166.024 that needs a service. I do not want to take it to an omega service center. I prefer an independent watchmaker who works on lots of omegas. I could send it to Nesbits in Seattle but would prefer a local watchmaker. Any referrals in the OC would be greatly appreciated.
