Abstract: A torsion resonator comprises an elongated torsion bar made in one flat piece with anchor-shaped ends supporting masses and an enlarged median zone at one side of which it is fixed by an elastically deformable branch to the bottom plate of a timepiece. An electrical transducer maintains torsional oscillation of the resonator and the relatively high torsional moment of inertia of the median zone compared to the rest of the bar prevents torsional efforts being transmitted to the supporting branch. Cooperating parts at the ends of the torsion bar and on the plate limit the amplitude of displacement of the torsion bar about the elastic branch.

Abstract: A digital display timepiece having a panel of display elements which change their optical properties when electrically excited, an electronic circuit, the outputs of which are connected to the display elements, and a time base controlling the logic circuit, such that excitation of various sub-assemblies of said display elements controlled by the logic circuit displays the desired time, where the logic circuit and the display panel are so connected as to constitute a monolithic unit having a minimum number of input connections linking the output of the time base to the logic circuit.

Abstract: Dial (20) for a timepiece (300)
including a dial plate (21), at least one dial foot (22) extending along a foot axis (A1) and having a shaping (231), notably a notch (23), oriented toward the dial plate and intended to receive a mechanical action that presses the plate against a clockwork movement (10), particularly against a frame (11) of a clockwork movement (10),
and a first zone (40) of lower rigidity configured or arranged to deform elastically and/or plastically, in a direction mainly parallel to the axis (A1) of the foot, as the mechanical action is applied to the shaping (231), a portion of the first zone being provided with a lower material profile so as to constitute a portion of the dial that is able to be mainly deformed or experience most of the deformation, and a flexible blade of the first zone extending substantially perpendicular to the axis (A1) of the foot and set into the rest of the foot at one of its ends.
