How about an atomic clock? Just like other metric systems of measurement, it's based on a repeatable scientific process instead of a arbitrary unit of measurement.

The problem with both time and space being defined by a "repeatable process", is that neither process used, for time or distance, are repeatable in any sense of the word.
If a second is formally defined as "9,192,631,770 vibrations of the unperturbed ground-state hyperfine transition frequency of the caesium-133 atom" (this is the SI definition)
And a meter is formally defined as the length of the path travelled by light in a vacuum in 1/299792458 of a second, (it is), then how fast can your car go?
Nobody, even the scientists running the atomic clocks can actually repeat the process so that they can say. While almost anybody can measure the speed of a car, in miles and hours.
