Abstract: Transmission device (100), for example for a watch mechanism (110), in particular for a winding train (100, 201) of a watch movement (120), including an input element (6) intended to be driven only in a first direction, an output element, a first mechanical connection arranged such that the displacement of the input element in a first direction causes the displacement of the output element in a second direction, and a second mechanical connection (9′, 9) arranged such that the displacement of the input element in the first direction causes the displacement of the output element in a third direction, the third direction being opposite the second direction.

Abstract: A timepiece glass, in particular a watch glass, wherein it comprises an optical device comprising at least one lens intended to enlarge an indication supplied by a timepiece, said lens comprising at least one aspherical face comprising at least one section passing through a vertical plane comprising an optical axis of vertical direction z, of which at least one outline can be defined by the following equation: z ⁡ ( r ) = r 2 R ⁡ ( 1 + 1 - ( 1 - κ ) ⁢ ⁢ r 2 R 2 ) + α 4 ⁢ r 4 + α 6 ⁢ r 6 + … in which R is the nominal radius of curvature, k is the constant of conicity, and α(4,6, . . . ) is or are coefficient(s) of asphericity, and in which at least the constant of conicity k and/or at least one coefficient of asphericity is different from zero.
