Abstract: A timepiece includes a mechanical oscillator, formed by a balance and a piezoelectric balance spring, and a regulating device for regulating the frequency of the mechanical oscillator which is arranged to be able to produce time-separated regulating pulses, each consisting of a momentary decrease in an electrical resistance applied by the regulating device between two electrodes of the balance spring relative to a nominal electrical resistance. Each regulating pulse produces a variation of rate which varies as a function of its moment of starting in a half-period of the mechanical oscillator, the characteristic function of this variation of rate relative to the moment of starting of at least one regulating pulse respectively in at least one half-period of the mechanical oscillator being negative in a first temporal zone of at least one half-period and positive in a second temporal zone of at least one half-period.

Abstract: A portable object includes a near-field communication device. The communication device includes an electronic chip provided with two terminals connected to an electrical circuit including an antenna and a filter. The communication device is provided to receive and transmit at a defined frequency corresponding to the resonance frequency of the electrical circuit. The portable object includes a control element which is able to be displaced between two predefined positions, i.e. an active position in which the communication device is activated and a passive position in which the communication device is deactivated. The electrical circuit includes, furthermore, a bypass branch provided with a mechanical switch which is able to switch between an open state and a closed state in response to a displacement of the control element from one to the other of its predefined positions causing a modification in the resonance frequency of the electrical circuit.

Abstract: A process for producing a metal alloy balance wheel by molding, the process including the following steps: a) making a mold in the negative shape of the balance wheel, b) getting hold of a metal alloy that has a thermal expansion coefficient of less than 25 ppm/° C. and is able to be in an at least partly amorphous state when it is heated to a temperature between its glass transition temperature and its crystallization temperature, c) putting the metal alloy into the mold, the metal alloy being heated to a temperature between its glass transition temperature and its crystallization temperature so as to be hot-molded and to form a balance wheel, d) cooling the metal alloy to obtain a balance wheel made of the metal alloy, e) releasing the balance wheel obtained in step d) from its mold.

Abstract: A timepiece includes a mechanical movement with a mechanical oscillator and an electronic device for regulating the medium frequency of this mechanical oscillator. It includes an electromagnetic transducer and an electric converter which includes a primary storage unit for powering the regulation circuit. The electromagnetic transducer is arranged to supply a voltage signal exhibiting first voltage lobes in first half-alternations and second voltage lobes in second half-alternations of the oscillations of the mechanical oscillator. The regulating device includes a load pump arranged to transfer electric loads from the primary storage unit into a secondary storage unit, these electric loads being extracted selectively in different time zones according to a time drift detected in the functioning of the mechanical oscillator relative to an auxiliary oscillator, particularly quartz-based.

Abstract: A method for maintaining and regulating frequency of a timepiece resonator mechanism around its natural frequency, the method including: at least one regulator device acting on the resonator mechanism with a periodic motion, to impose a periodic modulation of resonant frequency or quality factor or a position of a point of rest of the resonator mechanism, with a regulation frequency between 0.9 times and 1.1 times the value of an integer multiple of the natural frequency, the integer being greater than or equal to 2 and less than or equal to 10, and the periodic motion imposes a periodic modulation of the quality factor of the resonator mechanism, by acting on losses and/or damping and/or friction of the resonator mechanism.

Abstract: A temperature-compensated resonator including a body used in deformation, and a core of the body is formed by a material that is one of glass, ceramic glass, technical ceramic, and metallic glass. At least one part of the body includes a coating whose Young's modulus variation with temperature is of an opposite sign to that of the material used for the core, so that at least a first order frequency variation with temperature of the resonator is substantially zero.

Abstract: Altitude measurement device including an atmospheric pressure sensor arranged to be compressed or to expand in a rectilinear direction as a function of the atmospheric pressure to be measured which increases or decreases, wherein the movements of deformation of the atmospheric pressure sensor are transformed, via a transmission system, into a pivoting motion, in a plane perpendicular to the rectilinear direction of deformation of the atmospheric pressure sensor, of an activation system which drives the pivoting of an indicator hand, wherein the indicator hand moves over a graduated circular scale, wherein the atmospheric pressure sensor is arranged to be able to be moved in one direction or in the opposite direction depending on the rectilinear direction of deformation thereof relative to the other components of the altitude measurement device, wherein the atmospheric pressure sensor is mounted on a seat which is fixed in a support, which forms a case with a cover.

Abstract: Method for cutting a watch crystal along a contour in a plate of transparent material, with the following steps: making, on a first side of the plate, a first cut line or kerf to form a first chamfer, for each crystal of the plate; turning the plate over and marking the position of the first chamfers or of a previously made machined marking; making, on a second side, a second cut line or kerf to form a second chamfer, for each crystal; separating the crystals by machining through the plate at each contour to form an edge of the crystal.
