The present invention relates to a mechanical stop and start system for a function of a timepiece, comprising a mass, mounted so as to be able to move on a frame, between a first and a second end position, these being defined respectively by a first stop and a second stop, said mass moving in a bistable manner, under the effect of gravity, tensioning a spring between the first and second end positions, and relaxing said spring between the second and first end positions.

The invention relates to systems and methods for behavioral modification of users in an online community where users store or share data to help one another reach informed decisions. One aspect of the invention provides a method for encouraging active participation in an online community. The method includes: receiving information from a first user regarding a topic, receiving a request from a second user for additional information desired from the first user, and sending a personalized message to the first user requesting the additional information. Another aspect of the invention provides a computer-readable medium whose contents cause a computer to perform a method for encouraging active participation in an online community. The method includes: receiving information from a first user regarding a topic; identifying additional information desired from the first user; and sending a personalized message to the first user requesting the additional information.

A movement includes a tourbillion block, a tourbillion unit, and a zero reset mechanism. The tourbillion unit includes a carriage, a balance wheel, and an escape wheel. The balance wheel and the escape wheel are rotationally arranged on the carriage. The carriage is rotationally supported on the tourbillion block. The zero reset mechanism includes a first wheel in engagement with the escape wheel. The movement is switchable between a driving mode and a reset mode. When in the driving mode, the zero reset mechanism is rotationally locked to the tourbillion block. When in the reset mode, the zero reset mechanism is rotatable relative to the tourbillion block.
