An apparatus and method for a wall clock AI voice assistant, such as a computing device, is provided herein. The wall-mountable electronic clock includes an optical sensor, a microphone, a digital display and a speaker. The optical sensor captures image data representing at least a portion of a user. The microphone receives an audio input from the user when certain criteria is met, such as when the image data representing at least a portion of the user is captured. The digital display provides visual information to the user provided in response to the captured image data or the audio input. The speaker provides audio information provides from a digital voice assistant in response to the captured image data or the audio input.

A method for reference time setting of the displays (4; 5) of a sympathetic watch (200) by a sympathetic clock (100) forming a sympathetic assembly (1000) with the watch (200) which includes a coupling mechanism (706) between its display and finishing gear trains, and a hammer (701) movable between a coiled position where it is retained by a pawl, and an active position where it rests on an hour heart cam (702) carried by an hour wheel (708) of said watch (200), to constrain it in rotation to its smallest radius.

A horological display mechanism with an elastic hand (1) for driving, about a shaft (D), pipes mounted at the ends of a flexible blade (3), arranged to deform the flexible blade (3), including a mechanism acting on the drive train of the first pipe (2) and of the second pipe (4) and which includes two planetary wheels (82; 84) for driving the pipes (2; 4), and an input planet-carrier chassis (180) for driving the hand (1), and rotatable with a regulation cam (801), the track (802) of which includes a rising edge and falling edge. An elastic arm (803) has a distal end which cooperates with the track and a rising edge of which raises the elastic arm (803) away from the axis of the cam to consume torque, and a falling edge which makes the elastic arm move back towards the axis to restore torque to the system.
