Claims15
A mechanism comprising a measuring system mechanically connected to a display system for displaying time-related or other information and comprising a quick correction device with an epicycloidal gear train which can correct said display of time-related or other information at any time and by a predetermined step while maintaining the relationship between the display system and the measuring system during a correction phase, wherein the correction device includes an external planetary wheel connected at outer toothing thereof to the gear train of the measuring system and at inner toothing thereof to at least one satellite gear, wherein said at least one satellite gear is permanently meshed between said external planetary wheel and an internal planetary wheel and is connected to the gear train of the display system, and wherein the internal planetary wheel is connected to a correction means so that, via said at least one satellite gear, the gear train of the display system is moved by the gear train of the measuring system or by the correction means without inducing stress in the gear train of the measuring system.
