A portable object comprises a case forming a housing inside which is arranged a device that requires air to operate, and a closure device comprising at least one permeable element. The closure device is arranged to provide impermeability to liquids while allowing the atmosphere inside the housing to communicate with the external atmosphere. The case comprises a recess in which a through opening is made, said recess being closed by said closure device. The closure device comprises a permeable module mounted to move such that, in a gaseous environment, the permeable module is in a rest position allowing gases to penetrate said case opening through said permeable module, and in a liquid environment, the permeable module is in an operating position in which gases and liquids are blocked. The permeable module comprises a tubular support at the end of which is fixed a membrane.

The invention concerns a pressure sensor including means of sensing pressure and converting pressure into an electrical signal able to be transmitted by an electrical circuit to an control interface circuit of an indicator device, wherein said sensing and conversion means include: a closed volume and a liquid contained in the closed volume, said liquid being electrically conductive and capable of moving inside said closed volume, at least one sensing member arranged inside the closed volume in a given position in said volume, said sensing member including at least one pair of electrodes and cooperating with the liquid when said liquid moves in the closed volume, so that said electrical circuit is closed when the liquid passes said sensing member. The pressure sensor is intended to be integrated in a pressure measuring device, particularly a timepiece.

A smart watch comprises a case, a display device configured to present a user interface disposed in substantially all of a face of the case, a bezel around the display device configured to be rotated to select a mode of operation of the smart watch, and an analog first watch arm and an analog second watch arm disposed over the display, the second watch arm coaxial with the first watch arm. In a first mode of operation, the user interface presents a watch dial and control the first and second watch arms indicate a time of day first and second watch arms to indicate a time of day. In a second mode of operation, the user interface presents a dial and control the first and second watch arms form a pointer, the pointer configured to indicate a reading on the dial.

An electronic timepiece includes: a 6 o'clock information display unit that displays one display mode among a plurality of display modes including a barometric display mode in which a barometric pressure is displayed, using a first display hand; a 10 o'clock information display unit that displays a change in the barometric pressure using a second hand in a case in which the display mode displayed by the 6 o'clock information display unit is the barometric display mode; a 2 o'clock information display unit that displays the barometric pressure using measurement display hands in the case in which the display mode displayed by the 6 o'clock information display unit is the barometric display mode; and a time display unit that displays a time using an hour hand and a minute hand irrespective of the display mode.

A timepiece includes a display unit including a first indicating hand and a dial so as to display a time, in which the dial has a first scale having a number for showing an absolute value of a positive numerical value within a plurality of numerical values indicated by the first indicating hand, a second scale having a number for showing an absolute value of a negative numerical value within the plurality of numerical values, a first sign for showing that the numerical value indicated by the first indicating hand is positive, and a second sign for showing that the indicated numerical value is negative.

A housing includes: a housing body, having a cavity therein, with a first through hole in an outer wall thereof. The first through hole is in communication with the cavity, a first separate plate and a second separate plate are provided in the cavity, a gap between the first separate plate and an inner wall at one side of the cavity is in communication with the first through hole. A first recess for placing a water absorption device is provided between the first separate plate and the second separate plate, a bottom of a second recess between the second separate plate and the inner wall at another side of the cavity is in communication with the first through hole. A partial bottom of second recess close to first through hole is at a lower position than another partial bottom of second recess away from first through hole.

On-demand horological display mechanism, including a plurality of primary mechanisms each capable of determining the value of a variable, and at least one actuator that can be maneuvered by a user for the selection of the display of the instantaneous values of a specific variable determined by one of the primary mechanisms, each display being performed by the cooperation of a moveable display including a hand or a disc, with a complementary display including at least one graduated index, where the display and/or the complementary display is common to all of the displays that the display mechanism may produce.

A bracelet or strap for a watch case includes a first arm, inside which is housed a first printed circuit board portion, and a second arm, the first printed circuit board portion carrying at least one electronic component arranged to perform a corresponding electronic function, and a rigid electrical energy source and a microcontroller for powering and controlling the electronic component arranged to perform a corresponding electronic function, an actuating element, such as a push-button for inputting a control signal into the microcontroller being arranged above the rigid electrical energy source.
