Precision Voltage Reference 0.675V +- 0.005
Yes.

.675V +/- 0.005V is +/- 0.7%.

Digikey lists a lot of voltage references at 0.5% or better regulation.

Once you choose a reference, you can adapt the input voltage (if necessary) with a preregulator, and you can adapt the output voltage (if necessary) with a resistor divider.
