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 about which are pivoted: a) a units gear (61, 71) comprising a units disc bearing numerals corresponding to said units; b) a tens gear (51, 81) 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 (61, 71) to pivot; - a tens programming wheel arranged to be driven by said control wheel and to cause said tens gear (51, 81) to pivot; characterized in that: - said units programming wheel is arranged to cooperate with said units gear (61, 71) via a first self-blocking gearset (64, 61); - said tens programming wheel is arranged to cooperate with said tens gear (51, 81) via a second self-blocking gearset (55, 51); in that said tens gear (51, 81) is pivoted about said first axis of rotation by means of a tens ball bearing and said units gear (61, 71) is pivoted about said first axis of rotation by means of a units ball bearing; and in that a first (R1; R2) of said tens ball bearing and said units ball bearing is mounted on a support intended to be fixed to a frame element, a second (R2; R1) of said tens ball bearing and said units ball bearing being mounted between said tens gear (51, 81) and said units gear (61, 71). - a first axis of rotation about which are pivoted: a) a units gear (61, 71) comprising a units disc bearing numerals corresponding to said units; b) a tens gear (51, 81) comprising a tens disc bearing numerals corresponding to said tens; a) a units gear (61, 71) comprising a units disc bearing numerals corresponding to said units; b) a tens gear (51, 81) 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 (61, 71) to pivot; - a tens programming wheel arranged to be driven by said control wheel and to cause said tens gear (51, 81) to pivot; - said units programming wheel is arranged to cooperate with said units gear (61, 71) via a first self-blocking gearset (64, 61); - said tens programming wheel is arranged to cooperate with said tens gear (51, 81) via a second self-blocking gearset (55, 51); in that said tens gear (51, 81) is pivoted about said first axis of rotation by means of a tens ball bearing and said units gear (61, 71) is pivoted about said first axis of rotation by means of a units ball bearing; and in that a first (R1; R2) of said tens ball bearing and said units ball bearing is mounted on a support intended to be fixed to a frame element, a second (R2; R1) of said tens ball bearing and said units ball bearing being mounted between said tens gear (51, 81) and said units gear (61, 71). in that said tens gear (51, 81) is pivoted about said first axis of rotation by means of a tens ball bearing and said units gear (61, 71) is pivoted about said first axis of rotation by means of a units ball bearing; and in that a first (R1; R2) of said tens ball bearing and said units ball bearing is mounted on a support intended to be fixed to a frame element, a second (R2; R1) of said tens ball bearing and said units ball bearing being mounted between said tens gear (51, 81) and said units gear (61, 71).
