Abstract: A chronograph watch fitted with a going train including: a permanent seconds wheel set secured to a permanent seconds display member, a chronograph seconds wheel set cooperating with a coupling in order to be secured to a chronograph seconds display member, and a third wheel set including a first third wheel fixedly mounted in rotation, meshed either with the permanent seconds wheel set, or with the chronograph seconds wheel set, a second third wheel mounted to move freely, meshed with the permanent seconds wheel set and with the chronograph seconds wheel set.

Abstract: The invention concerns a fastening band (1) of the belt type or a wristband or bracelet for a portable device (40) for example, including fastening and length adjustment means (5). The fastening band includes an element (6, 42) for indicating the fastening tension thereof that has a specific visual appearance identifiable to the user in order to indicate to the latter when the fastening tension of the band is sufficient for a given application. The fastening band of the present invention is particularly interesting when it is implemented in the form of a wristband for a pulsometer worn on the wrist comprising optical type measuring means. In this application, a fastening tension value sufficient to guarantee proper measurement precision is predefined, the features of the indicator element being adapted to this value in order to indicate to the wearer that he has reached said value when the wristband is being fitted to his wrist.

Abstract: The electronic timepiece (10) includes a case (12) that contains at least one first and one second electronic module (14, 16) powered by a battery (18). The case (12) is formed by a middle part (20), which is closed by a protective crystal (22) placed above a display device (24) and by a cover (26) added to the case (12). The case (12) includes an added partition (32), which is secured to the middle part (20) and which delimits a top compartment (34) containing the first electronic module (14) and a bottom compartment (36) containing the second electronic module (16). The battery (18) is arranged in a complementary housing arranged in the bottom face (40) of the partition (32). A method of assembling the timepiece (10) is also provided.

Abstract: A device is described for establishing an electrical connection between a portable electronic instrument and an external device, the portable electronic instrument comprising a casing provided with a socket in which a plurality of electrical contact elements is disposed, this socket being shaped to permit the insertion of a plug-in adaptor which is electrically connected to the external device and comprises a plurality of electrical contact zones, each intended to come into contact with a corresponding electrical contact element in the socket. The electrical contact elements are disposed substantially perpendicularly to the direction of insertion of the plug-in adaptor, and the electrical contact zones extend substantially parallel to the direction of insertion of the plug-in adaptor. Also described is a system for recharging a battery of a portable electronic instrument comprising such a connection device, as well as a plug-in adaptor for such a connection device.

Abstract: The invention concerns a patch antenna (20) for a small-sized portable electronic instrument comprising a radiating element (21) separated from a ground plane (23) by a dielectric (22) and comprising feed (25) and ground (26) conductors for electrically connecting said radiating element and said ground plane (23) respectively, to an electric module (6). The ground plane (23) consists of a stamped metal plate including at least a folded foot (26a, 26b) outside said ground plane and directly connecting said ground plane (23) to said electronic module (6), said foot (26a, 26b) forming said ground conductor (26) of the antenna.

Abstract: The portable instrument with a wristband (4) includes an electronic circuit and a rechargeable power source for supplying the electronic circuit with electricity. The wristband includes two electric contact portions (10,11) arranged on a same strand (4) of the wristband and conductive paths (8, 9) connecting the power source. The two electric contact portions (10, 11) are intended to be placed on two complementary conductive portions of an electric charger to allow the power source to be recharged. A loop (12) can be brought into a blocking position above the contact portions (10, 11) to cover and protect them.
