Abstract
An electro-mechanic calendar timepiece includes a braking device for generating torque to prevent drifting or floating of the movement gearing when the intermittent calendar driving mechanism is not rotating. When the calendar driving mechanism is rotating the braking device is not operating and the calendar driving mechanism cooperates with a lever arm and spring to generate torque to prevent the floating of the movement gearing.
