Abstract
A timepiece movement comprises a rotor driven for intermittent rotation by a stepping motor, a speed-reducing wheel train and a second stop device. The speed-reducing wheel train has a movement conversion mechanism for transmitting intermittent rotary movement of the rotor to continuous rotary movement of a second hand wheel in a smooth manner. The second stop device is moveable between a first position, for immediately stopping the second hand wheel, and a second position, for immediately moving the second hand wheel at a predetermined speed.
