Notes
Simple stop feature:
The direct sweep second is continuously running, the second-hand arbor with heart disc is coupled to the fourth wheel with a latching axial clutch (Fig.3).
The pusher at 2h stops the second hand as long as held down.
The pusher at 4h resets the second to zero, and restarts it when released (poor man's flyback feature).
