The pendulum drive armature is of the early, solid type. Later examples had a roller.
This is a close up of the waiting train mechanism which controls the timekeeping of the turret, motor pendulum. A Pulsynetic master clock or impulse circuit will be required for a suitable dial and hands to keep good time. Without the brief, half minute impulse, the WT will run fast since it will not be paused as the designer's intended.
An authentic time setting crank is present. Useful for resetting the turret dial to time after a change to summer or winter time.,
