I am not so sure. Yes, the breathing mechanism is the same, but the exhaust valve and purge placement or other aspects of the design might be different? I personally am not clear on the differences and I think a factory rep's input would be very useful here.
I am definitely going to get one of these regs, as I was a Tekna/Omega servo regulator diver in the 80s and they were absolutely without equal.
I am thrilled to see the return of the Omega, but, like burhan, I would like to have more information on the differences.
