Anatomy of
a second.

Like a pendulum small enough to live on your wrist, it repeats an oscillation. The escapement supplies small impulses to sustain that motion.

This procedural model illustrates relationships using a shared animation clock. It is not a physics simulation or a watchmaking service guide. The hairspring has a fixed outer attachment and a moving inner attachment; its deformation does not conserve exact spring length. The escapement has timed locking and release phases, but its contact geometry has not been mechanically validated.
