Mechanism for displaying a horological value composed of a units numeral and of a tens numeral at least when the latter is greater than zero, said mechanism comprising: - a first axis of rotation (A1) about which are pivoted: a) a units gear comprising a units disc bearing numerals corresponding to said units; b) a tens gear comprising a tens disc bearing numerals corresponding to said tens; - a control wheel arranged to be driven in steps of 1/ n of a revolution under the control of an input wheel intended to be driven by a base movement, n being a non-zero natural whole number; - a units programming wheel arranged to be driven by said control wheel and to cause said units gear to pivot; - a tens programming wheel arranged to be driven by said control wheel and to cause said tens gear to pivot; characterized in that : - said units programming wheel is arranged to cooperate with said units gear via a first self-blocking gearset ; - said tens programming wheel is arranged to cooperate with said tens gear via a second self-blocking gearset ; in that said tens gear is pivoted about said first axis of rotation (A1) by means of a tens ball bearing (R1) and said units gear is pivoted about said first axis of rotation (A1) by means of a units ball bearing (R2); and in that a first (R1; R2) of said tens ball bearing (R1) and said units ball bearing (R2) is mounted on a support intended to be fixed to a frame element, a second (R2; R1) of said tens ball bearing (R1) and said units ball bearing (R2) being mounted between said tens gear and said units gear . - a first axis of rotation (A1) about which are pivoted: a) a units gear comprising a units disc bearing numerals corresponding to said units; b) a tens gear comprising a tens disc bearing numerals corresponding to said tens; a) a units gear comprising a units disc bearing numerals corresponding to said units; b) a tens gear comprising a tens disc bearing numerals corresponding to said tens; - a control wheel arranged to be driven in steps of 1/ n of a revolution under the control of an input wheel intended to be driven by a base movement, n being a non-zero natural whole number; - a units programming wheel arranged to be driven by said control wheel and to cause said units gear to pivot; - a tens programming wheel arranged to be driven by said control wheel and to cause said tens gear to pivot; - said units programming wheel is arranged to cooperate with said units gear via a first self-blocking gearset ; - said tens programming wheel is arranged to cooperate with said tens gear via a second self-blocking gearset ; in that said tens gear is pivoted about said first axis of rotation (A1) by means of a tens ball bearing (R1) and said units gear is pivoted about said first axis of rotation (A1) by means of a units ball bearing (R2); and in that a first (R1; R2) of said tens ball bearing (R1) and said units ball bearing (R2) is mounted on a support intended to be fixed to a frame element, a second (R2; R1) of said tens ball bearing (R1) and said units ball bearing (R2) being mounted between said tens gear and said units gear . in that said tens gear is pivoted about said first axis of rotation (A1) by means of a tens ball bearing (R1) and said units gear is pivoted about said first axis of rotation (A1) by means of a units ball bearing (R2); and in that a first (R1; R2) of said tens ball bearing (R1) and said units ball bearing (R2) is mounted on a support intended to be fixed to a frame element, a second (R2; R1) of said tens ball bearing (R1) and said units ball bearing (R2) being mounted between said tens gear and said units gear . <EOS>
