Abstract (en)
[origin: EP1544691A1] The timepiece has a hand fitted onto an hour pipe, about which an hour hand is adjusted to freely pivot by a motion work. An additional wheel (12) secured to the pipe, drives an additional device. An hour wheel (2) is rigidly coupled to the additional wheel by a limiting torque mechanism and a coupling mechanism. A spring is immobilized and compressed in a space between two teeth of a star wheel.
