Swiss lever escapement

3D model with a harmonically oscillating balance; the pallet fork and escape wheel follow it as calculated by our escapement simulator. Amplitude is measured in the watchmaking convention: the angular displacement to one side. Drag to rotate, use the mouse wheel or two fingers to zoom, and right-drag to pan.

Swiss lever escapement with a 15-tooth club-tooth escape wheel. The cocks, bearings, shock settings and regulator are shown semi-transparent to keep the escapement visible. The pallet stones, banking pins and guard pin occupy the positions of the adjusted escapement in the simulator.
