Video explanation
A dark-mode recording shows gears, a balance and a watch movement, alternating close and wider views. Transmission and oscillation parts remain visible despite the dark image.
Gear transmission
Meshing gears transmit rotation; tooth-count ratios determine relative speeds.
Oscillation for timing
A balance oscillation provides a time reference while an escapement meters energy into timed steps.
Drawing and hardware
Dark rendering affects readability but not the intended relationships. The recording cannot establish every tooth profile or real caliber specification.
