A battery-powered clockwork mechanism and a separate pendulum unit which is detachably connected to the clockwork mechanism. When so connected the pendulum device is powered by the battery in the clockwork mechanism but operates as a "blind" pendulum which does not control or affect the time-keeping function of the clockwork mechanism.

A torsion pendulum clock in which the rotating pendulum performs no regulating functions and is driven by an electrical actuator independent from the clockwork; the actuator is accommodated under the pendulum in a housing in the base of the clock.

A mechanical-type watch movement is disclosed. In one implementation, the movement may include a frame. The frame may support a work train that is periodically driven in rotation by a driving element. The frame may also support an animation part. The animation part may be configured to be visible, and may be arranged to be animated by an oscillating movement that is capable of simulating, for example, a pendulum movement. The movement may also include, supported by the frame, an animation train that meshes with a mobile of the work train, and is kinematically connected to the animation part.

A simulated clock apparatus utilizes a housing having an opening therein and a shelf disposed in the housing below the opening. A conventional wristwatch is adapted to be rested on the shelf so as to have the face of the clock exposed for external viewing through the opening. A pendulum is pivotably secured to the shelf and is displayed visibly through a second opening located below the opening. The pendulum may be continuously oscillated back and forth in conventional "Grandfather Clock" fashion by a bar passing through a solenoid coil, such that the bar is urged into oscillatory motion, when contacting an electrical switch at an end thereof such that the switch is operated into a closed position causing a current flow from the battery, housed within the housing, to exert a pulling force on a ferromagnetic portion of the center of the bar. When the bar moves away from its displaced non centric position towards a rest position, the switch is opened causing the current flow to cease such that the momentum of the bar causes an override and continued oscillation until the next cycle wherein the switch again is urged into a closed position by contacting the end of the bar. The pendulum, by moving back and forth, creates a miniature effect of a "Grandfather Clock," coupled with the actual operating of the wrist-watch hand. The wrist-watch may be secured into the storage position within the housing utilizing a block of foam rubber-like material.
