An analogue display watch () including an electronic horological movement including a first and a second electric motor () kinematically connected respectively to an hour hand () and to a minute hand (), the electric motors being power supplied by an electric accumulator (), the horological movement also comprising an integrated circuit () connected to the motors and to a control member (), the watch () being characterised in that the integrated circuit () is configured so as to control, when the control member () is requested by a user, the first and the second electric motor () to rotate the hour () and minute () 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.

Watch comprising an auxiliary function allowing the indication of seconds

A timepiece including a case; pivotably mounted display hands; a movement to drive the display hands while defining a sweeping surface; a display screen, a first part of the sweeping surface being superimposed on the screen and a second part of the sweeping surface not being superimposed on the screen; a control circuit configured to sequentially switch between first and second operating modes, with: a first operating mode wherein the display hands are driven in the first and second parts of the sweeping surface; a second operating mode wherein the display hands are driven only in the second part of the sweeping surface with display of a piece of information by the display screen.

Timepiece combining display hands and a digital display screen

An electronic module including at least one electric motor for driving an analog display, a clock module including a time base delivering a clock signal connected to a divider circuit, the divider circuit delivering a reference signal sent to a control circuit arranged to control the electric motor, the clock module further including a measuring and correction circuit arranged between the time base and the divider circuit and delivering an intermediate compensated signal. The time base, the compensation module, the divider circuit, and the control circuit are arranged in a same case to form the clock module.

Thermocompensated chronometer circuit

An electromechanical or digital watch includes a middle part that delimits with a glass a watch case. The glass includes an upper surface oriented upwardly, and a lower surface oriented towards the watch case. The watch also includes a dial made of an electrically non-conductive material. The dial includes a lower surface and an upper surface located opposite the watch case. Electrically conductive paths for the connection of one or more electronic components are structured on at least one of the lower or upper surfaces of the dial. The watch includes a flange that ensures, via the electrically conductive paths, the electrical connection between an electronic device arranged on the lower surface of the glass and the electronic components. The flange supports the dial or is made in one-piece with the dial.

Electromechanical or digital watch including a dial and method of manufacturing such a dial

Wristwatch comprising a mechanical device for executing a first mechanical function arranged to produce a first acoustic alarm signal, and an electronic device housed in a bracelet and arranged to produce a second acoustic alarm signal and/or a mechanical vibration, wherein the electronic device is arranged to produce the second acoustic alarm signal at the moment when the mechanical device for executing the first mechanical function produces the first acoustic alarm signal.

Navigation aid instrument for an aircraft pilot including:

Navigation aid instrument for aircraft

Watch comprising a middle part which, with a crystal, delimits a watch case. The crystal includes a top face facing the user and an opposite bottom face facing the watch case. An electronic device is arranged on the bottom face of the crystal. A printed circuit board is disposed inside the watch case, underneath and remote from the electronic device. The watch includes a flange which is disposed between the crystal and the printed circuit board. The flange carries an electrical connection between the electronic device and the printed circuit board.

Watch including a flange

Electromechanical timepiece fitted with a gear train including an hour hand and a minute hand for the current time display on the dial side of the timepiece. The timepiece is arranged to provide at least one additional piece of information relating to a magnitude of time, or to a non-time related piece of information. The timepiece further includes an additional indicator hand arranged to display the additional information, the additional indicator hand being mounted on the back cover side of the timepiece on an arbour of the gear train of the timepiece, so that the additional indicator hand and the hour hand and/or minute hand rotate at the same time and at the same angle, the hour hand and/or the minute hand being driven either to display the current time, or to enable the additional indicator hand to indicate the additional information.

Electromechanical timepiece provided with an additional function

A wristwatch includes a bezel, a series connected photovoltaic cell, a rechargeable battery, and an electronic device. The bezel defines an internal volume, which houses the photovoltaic cell, the rechargeable battery, and the electronic device.

Exterior element for a wristwatch

A method is provided to authenticate a watch. The watch includes at least one processing and control circuit provided with a time base, hands to indicate a time, the hands being driven by a motorized device controlled by the processing and control circuit, and a device to store identification data. The method includes enabling at least one activation member of the watch, which is connected to the processing and control circuit, to change into watch authentication mode. The method includes operating an indicator device of the watch, which includes the hands, after enabling the activation member so that at least one of the hands is driven by the motorized device to be moved in succession into time indicating positions on a time-indicating dial to indicate successive digits or numbers of an identification code of at least one of a brand and a serial number of the watch to be authenticated.

Method for authenticating an electronic watch and electronic watch for implementing the method

An external element for a wristwatch, containing an electronic device and a power source for powering the electronic device with electric energy, wherein the electronic device and power source are integrated in the exterior element, to form an autonomous electronic module, which is completely independent of the wristwatch movement.

The invention concerns a timepiece () including a display device () including a first and second display member () displaying first and second pieces of information, the value of the second piece of information being linked to the value of the first piece of information by a reduction ratio, wherein the first () and the second () display members are rotatably mounted in relation to a plate () and are driven by a drive device () with planetary gears, characterized in that the second display member () pivots on the axis of rotation (A) of a planet pinion (). The invention also proposes a timepiece () fitted with this display device () and a method for manufacturing this display device ().

Analogue display device including a planetary gear device

The invention relates to a timepiece () fitted with a glass () having an inside face and an outside face to the timepiece and a lighting device () comprising at least one ultraviolet or infrared light-emitting diode () to illuminate at least one zone () integrating fluorescent and/or phosphorescent pigments of an indicator element () visible through the glass, characterized in that the light-emitting diode is arranged on the periphery of the glass forming a waveguide capable of diffusing the ultraviolet or infrared light, and that means for diffusing ultraviolet or infrared light () from the glass towards the interior of the timepiece are arranged in the path of the ultraviolet or infrared light.
