Abstract (en)
[origin: US2016274542A1] Timepiece movement including a date display drive device formed of a display disc including a toothing, said drive device including driving means and a drive source. The driving means includes a wheel set including pins, having a toothed wheel and a pinion including pins, and an engaging wheel engaging said toothed wheel. The pinion with pins includes a pair of pins configured to be positioned on either side of any tooth of the toothing. The toothed wheel of the pin wheel and the engaging wheel respectively have complementary non-circular profiles. When the two pins are oriented in a tangential direction to the toothing, these two wheels have a first gear ratio that is lower than a second gear ratio between them when the two pins are in perpendicular alignment to said tangential direction.
