⌚ Mechanical Escapement Lab: Swiss Lever, Pendulum Clock and Isochronism

See how a mechanical clock keeps time: a Blender-modelled Graham deadbeat pendulum clock and a Swiss lever watch movement (escape wheel, pallet fork, balance wheel with breathing hairspring, gear train), driven by an interactive escapement-plus-oscillator model with live amplitude, rate (s/day), beat error and energy-per-beat graphs. Unlike the existing clock-mechanism and wristwatch pages it computes isochronism error (circular error, recoil vs deadbeat, hairspring defect), the steady amplitude from the energy balance and temperature drift, with four measured-vs-predicted experiments.
