Can an astronaut in a weightless state use a clock set in motion by a weight? a twisted spring?

In spring clocks and clocks with a weight, potential energy is used to operate the mechanism.

The weight energy is determined by the formula

Eg = mgh.

in the state of zero-gravity

g = 0,

so

Eg = 0.

Such a clock will stop in zero gravity.

The potential energy of the spring is determined by the formula

Ep = k * x² / 2,

does not depend on the conditions of weightlessness.

Answer: an astronaut in a weightless state cannot use a clock with a weight; can use a watch with a wound spring.
