You need to define “accurate”

For the caveman, the sun rising and setting was accurate enough for their daily lives

For the roman senate the sundial and a hourglass was accurate enough to know how long to to debate.

For traders on the sailships a spring loaded pocket watch was accurate enough to know time.

For the factory worker a DC powered clock was enough to know when to take a lunchbreak.

A crystal oscillator clock for a computer to have everything in sync.

For a scientist an atomic clock is accurate enought to measure subatomic processes.
