Multiple jump timepiece display mechanism

A multiple jump timepiece display mechanism, arranged to be driven by an input mobile moved by a movement, for the display of a variable over a plurality of discrete positions, by at least one display opposite a display scale, said discrete positions being separated two by two by intervals, each interval being equal to an elementary pitch PE, or to an increased pitch PM greater than said elementary pitch PE, or to an integer multiple of said elementary pitch PE, and at least one said interval being different from the others, said mechanism comprising:

• a gear train for controlling the movement of said display, which comprises a continuously rotating control wheel driven directly or indirectly by said input mobile or constituting said input mobile, and which is arranged to drive an indicator wheel carrying said at least one display, either through an elementary pitch drive mechanism, directly by the value of said elementary pitch PE by a direct or indirect continuous cooperation, or indirectly through a multiplier mechanism, by a means for disengaging said elementary pitch drive mechanism, and by driving said indicator wheel, in at least one disengaging position, by said multiplier mechanism driving it by said increased pitch PM greater than the elementary pitch PE, said indicator wheel including a coaxial and synchronous lower level having complete toothing and engaged with a first jumper for maintaining the display position and upper level cooperating directly or via a direct gear train with said control wheel over part of a circumference of the control wheel, and including a locally truncated toothing, each truncated area constituting said means for disengaging for interrupting the kinematic chain between said upper level and said control wheel.
