For this sketch I removed the movement from a 1945 Waltham mechanical manual wind watch. I filmed at 240 frames per second in order slow down the motion of the individual components in order to see how they interfaced. The first half of the video shows the second hand moving as well as some small movements of the internal components. In the second half of the video you can see the escapement oscillating between its two positions as well as the flywheel rotating back and forth between its start and end positions.
