Aperture setting information is coupled to the metering circuit through a variable resistor.
It's continuously adjustable, like the volume control on a classic radio or television (some modern ones are digital).

The 'resolution' would be 1/10000 of an f-stop or better.

The concept of 'resolution' is only meaningful in digital systems.
Nikon pre-digital cameras are completely analog.
