Because the frequency of oscillation is very constant. It doesn't depend on the length of the swing.
However it is quite useless for wrist-watches, digital clocks and clocks in space.

Actually, a gravity pendulum is not ideally suited for a clock because its rate depends on local gravity, which varies significantly from place to place. A spring-driven pendulum is well suited because any two identical spring pendulum clocks will still be in pretty good agreement after being separated for a long time and brought back together---provided they are kept at about the same temperature, and not accelerated to relativistic speeds.
With clever compensation for the effects of temperature, spring pendulums were the most dependable clock references known until the mid 20th century.

A long as the pendulum travels a small distance (i.e., not flipping around in complete circles), stays the same length, and stays on the surface of the Earth, the oscillations will always have the same period.
That means it will always take the same amount of time for the pendulum bob to swing back and forth one time. That makes it a good device for keeping track of time.

Cos it keeps going, like and there's no cursed damping to be concerned about
