A timepiece movement includes a photovoltaic cell which is attached to the upper surface of a support plate, preferably by adhesive bonding. On the other side of the cell, on its lower surface, the support plate is provided with a plurality of nuts. An electrical module including a flat surface is attached to the support plate with the nuts. The module is provided with several openings whose position and dimensions correspond to those of the nuts, so that the nuts pass through the openings, allowing the flat surface of the module to be placed in contact with the support plate. The module is secured to the support plate by screws, screwed into the nuts. The connection via the nuts secures the photovoltaic cell to the electrical module and ensures shock resistance, without requiring a lateral support.

An analogue display watch (10) including an electronic horological movement including a first and a second electric motor (13, 14) kinematically connected respectively to an hour hand (15) and to a minute hand (16), the electric motors being power supplied by an electric accumulator (12), the horological movement also comprising an integrated circuit (17) connected to the motors and to a control member (18), the watch (10) being characterised in that the integrated circuit (17) is configured so as to control, when the control member (18) is requested by a user, the first and the second electric motor (13, 14) to rotate the hour (15) and minute (16) hands at an angular speed of displacement of six degrees per second, and in such a way that they are disposed so as to be collinear and that they are superimposed on each other.

Clock with mechanical movement motif that incorporates a clock movement with a movement of a selected mechanical part. The clock may be wall mounted or may include an upright stand having a base and an attachment to a mounting frame. The mounting frame includes an adapter flange for attachment of a clock works mechanism. The movement shafts of the clock mechanism are carried through an aperture extending through a face of the mounting frame. A front face of the mounting frame includes a spindle with index notches for cooperative engagement with a clock face. A bushing has an inner diameter that is adapted to be rotationally carried on the shouldered region of the spindle. An outer diameter of the bushing is adapted to carry a bore of a mechanical part. A motor and drive sprocket are coupled to the bushing for rotation of the mechanical part about the spindle.

Regulating body for a wristwatch, comprising: a generator provided with a rotor and a stator with M+N coils, M being a whole number higher than, or equal to, 1; and an electronic regulating circuit having a first load impedance with an adjustable value for adjusting the current in N of said M+N coils, and therefore the rotational speed of the rotor. Only a limited number of coils is therefore used for the braking, the other coils continuing to supply the electronic regulating circuit.

An electronic watch includes a power generating mechanism; a battery that is charged with power generated by the power generating mechanism; hands that include a second hand; a driving source that rotates the hands; a driving circuit that drives the driving source with power supplied by the battery; and a control circuit that controls the driving circuit. The control circuit executes a first stopping operation for stopping the driving circuit and the control circuit in a power saving mode for suppressing power consumption and when a first determination time elapses without any power being generated by the power generating mechanism. The control circuit executes a second stopping operation for stopping the driving circuit and the control circuit in the power saving mode and when a second determination time elapses while a voltage of the battery is at a level equal to or lower than a predetermined level.

A method for manufacturing a plurality of generators, each intended to power supply an electronic circuit operating in a given power supply voltage range, includes a step of manufacturing coils distributed in N pluralities of coils, similar within the same plurality and different from one plurality to another, and a step of manufacturing a plurality of rotors which is carried out with tolerances limiting the cost of production. The plurality of rotors is classified into N classes of rotors which are associated respectively with the N pluralities of coils to form N pairs allowing the assembly of N groups of generators. The generators of each of the N groups of generators have magnetic coupling factors between their rotor and their stator which are located in a corresponding optimised value range, which is at least partially superimposed on the others of the N optimised value ranges relating to the N generator groups.
