Disclaimer
A procedural teaching model, not a replica of a production caliber. Tooth counts and the 18,000 vph rate are realistic and drive every animated ratio; wheel sizes, bridge shapes and the plan layout are simplified for clarity. The escapement motion is a kinematic model (timed release and impulse), not a physics simulation.
