hairsprings

Timepiece regulating spirals

Hairsprings are the thin, coiled springs in mechanical watches and clocks that regulate timekeeping.

The hairspring oscillates back and forth at a precise rate, controlling the movement of the balance wheel.

Also called balance springs.

The delicacy of these components makes them symbols of precision engineering: adjusted with hairspring sensitivity.
