Description

L'invention concerne une pièce d'horlogerie pourvue d'un mouvement automatique, mécanique ou électronique tel qu'un mouvement à quartz comprenant un dispositif de communication en champ proche de type NFC ou encore RFID, le dispositif de communication comportant une puce électronique connectée à une antenne.The invention relates to a timepiece provided with an automatic, mechanical or electronic movement such as a quartz movement comprising a near-field communication device of the NFC or RFID type, the communication device comprising a connected electronic chip. to an antenna.

Il est connu dans l'état de l'art d'équiper une pièce d'horlogerie d'un dispositif de communication en champ proche afin d'améliorer son suivi tout au long de sa durée de vie ou encore pour lutter contre les contrefaçons dont elle peut faire l'objet. Dans le cadre de son fonctionnement, le dispositif de communication est apte à se connecter à un périphérique associé lorsqu'il est situé à une distance proche de ce dernier et à lui transmettre un signal radio relatif à des informations la concernant.It is known in the state of the art to equip a timepiece with a near-field communication device in order to improve its monitoring throughout its lifetime or to fight against counterfeits of which it can be subject. As part of its operation, the communication device is adapted to connect to an associated device when it is located at a distance close to the latter and to transmit a radio signal relating to information about it.

De manière générale dans l'état de l'art, un tel dispositif de communication est disposé dans des composants de la pièce d'horlogerie comme le boîtier, la carrure, le bracelet ou encore la glace.Generally in the state of the art, such a communication device is disposed in components of the timepiece such as the case, the middle part, the bracelet or the ice.

Cependant, un inconvénient majeur d'un tel dispositif de communication ainsi agencé dans la pièce d'horlogerie est lié au fait qu'il souffre souvent d'un manque de fiabilité. En effet, l'agencement particulier de ce dispositif de communication dans des composants de la pièce d'horlogerie qui sont essentiellement métalliques, engendre de nombreuses perturbations électromagnétiques. De telles perturbations résultent de réflexions et/ou d'absorptions des signaux émis par le dispositif de communication lorsqu'il est à proximité du périphérique. Ces perturbations sont susceptibles d'entraîner des dysfonctionnements dans le cadre de l'établissement d'une connexion avec le périphérique ou encore du maintien de cette connexion.However, a major disadvantage of such a communication device thus arranged in the timepiece is linked to the fact that it often suffers from a lack of reliability. Indeed, the particular arrangement of this communication device in components of the timepiece which are essentially metallic, generates many electromagnetic disturbances. Such disturbances result from reflections and / or removals of the signals emitted by the communication device when it is close to the device. These disturbances are likely to cause malfunctions in connection with the establishment of a connection with the device or the maintenance of this connection.

Pour pallier cet inconvénient, il est courant d'utiliser dans l'état de l'art un dispositif de communication comprenant une antenne de grande taille. Toutefois, l'intégration d'une telle antenne dans la pièce d'horlogerie et en particulier dans ses composants est d'une mise en oeuvre complexe et fastidieuse. De plus, une telle intégration rend difficile toute intervention ultérieure sur la pièce d'horlogerie visant à assurer l'entretien et/ou la réparation de cette dernière.To overcome this drawback, it is common to use in the state of the art a communication device comprising a large antenna. However, the integration of such an antenna in the timepiece and in particular in its components is a complex and tedious implementation. In addition, such integration makes it difficult any subsequent intervention on the timepiece to ensure the maintenance and / or repair of the latter.

La présente invention vise à pallier de tels inconvénients liés aux pièces d'horlogerie de l'état de l'art.The present invention aims to overcome such drawbacks related to timepieces of the state of the art.

Dans la présente invention, la pièce d'horlogerie 35 est pourvue d'un boîtier 20 comportant une carrure 22 et un fond 24, visibles sur la figure 9. Le boîtier 20 de cette pièce d'horlogerie 35 est susceptible de recevoir un mouvement automatique, mécanique ou encore électronique comme un mouvement à quartz. Ce mouvement est surmonté d'un cadran 1 et d'un jeu d'aiguilles au-dessus desquels est agencée une glace 21. Cette pièce d'horlogerie 35 comprend également une lunette 2 qui peut être fixe ou tournante et qui est de préférence disposée au niveau du bord de la carrure 22.In the present invention, the timepiece 35 is provided with a housing 20 having a middle part 22 and a bottom 24, visible on the figure 9 . The housing 20 of this timepiece 35 is capable of receiving an automatic movement, mechanical or electronic as a quartz movement. This movement is surmounted by a dial 1 and a set of needles above which is arranged a mirror 21. This timepiece 35 also includes a telescope 2 which can be fixed or rotating and which is preferably arranged at the edge of the middle part 22.

Sur les figures 1 à 10 sont décrits des modes réalisation de la pièce d'horlogerie 35 comprenant un dispositif de communication 4 en champ proche apte à émettre/recevoir un signal ainsi qu'un écran magnétique 8.On the Figures 1 to 10 are described embodiments of the timepiece 35 comprising a communication device 4 in the near field capable of transmitting / receiving a signal and a magnetic screen 8.

Plus précisément sur les figures 1 à 8, un premier mode de réalisation de la pièce d'horlogerie 35 comprend le dispositif de communication 4 agencé au niveau du cadran. Dans un deuxième mode de réalisation de cette pièce d'horlogerie 35 représenté sur les figures 9 et 10, le dispositif de communication 4 est situé au niveau de la lunette 2 de la pièce 35.More precisely on the Figures 1 to 8 , a first embodiment of the timepiece 35 comprises the communication device 4 arranged at the dial. In a second embodiment of this timepiece 35 shown in FIGS. Figures 9 and 10 , the communication device 4 is located at the bezel 2 of the piece 35.

Ce dispositif de communication 4 met en oeuvre par exemple des technologies de communication sans fil à courte portée et à haute fréquence de type NFC (acronyme pour « Near Field Communication » en langue anglaise signifiant « communication en champ proche ») ou RFID (acronyme pour « Radio-Frequence Identification » en langue anglaise signifiant « identification par radiofréquence »). Ce dispositif de communication 4 peut fonctionner dans les bandes de fréquences suivantes :

  • basses fréquences LF par exemple entre : 125 kHz - 134,2 kHz ;
  • hautes fréquences HF par exemple à 13,56 MHz ;
  • ultra hautes fréquences UHF par exemple entre : 860 MHz - 960 MHz ;
  • super hautes fréquences SHF par exemple à 2,45 GHz.
This communication device 4 uses, for example, short-range and high-frequency wireless communication technologies of the NFC type (acronym for "Near Field Communication" in the English language meaning "Near Field Communication") or RFID (acronym for "Radio Frequency Identification" in the English language meaning "Radio Frequency Identification"). This communication device 4 can operate in the following frequency bands:
  • low frequencies LF for example between: 125 kHz - 134.2 kHz;
  • high frequencies HF for example at 13.56 MHz;
  • ultra high frequency UHF for example between: 860 MHz - 960 MHz;
  • super high frequencies SHF for example at 2.45 GHz.

De telles technologies permettent ainsi à la pièce d'horlogerie 35 de pouvoir échanger des informations à de courtes distances, avec d'autres périphériques associés. De telles distances peuvent être comprises entre environ 0 et 20 cm, et de préférence entre 0 et 2 cm. Ce dispositif de communication 4 peut être du type passif avec une énergie qui lui est fournie par les fréquences radio émises par chaque périphérique associé.Such technologies thus allow the timepiece 35 to be able to exchange information at short distances with other associated peripherals. Such distances may be between about 0 and 20 cm, and preferably between 0 and 2 cm. This communication device 4 may be of the passive type with an energy supplied to it by the radio frequencies emitted by each associated device.

De telles courtes distances entre la pièce d'horlogerie 35 et chaque périphérique associé permettent d'éviter toute activation involontaire d'établissement de connexion entre ces derniers et contribuent également à limiter toutes tentatives de connexion non autorisée pouvant résulter d'actes de piratage.Such short distances between the timepiece 35 and each associated device prevent unintended activation of connection establishment between them and also help to limit any unauthorized connection attempts that may result from hacking.

Plus précisément, ce dispositif de communication 4 en champ proche comprend une puce électronique 6 et au moins une antenne 5. La puce 6 qui est connectée à la dite au moins une antenne 5, comprend des éléments matériels et logiciels. Dans ce contexte, les éléments matériels et/ou logiciels de la puce 6 du dispositif 4 comportent plus précisément au moins un microprocesseur 13a coopérant avec des éléments de mémoire 13b. Cette puce 6 peut être apte à exécuter des instructions de code de programme pour la mise en oeuvre d'un programme d'ordinateur. Les éléments de mémoire 13b de cette puce 6 peuvent archiver des données relatives à des informations sur la pièce d'horlogerie 35 ou encore sur le porteur de cette pièce. On notera que dans une alternative, le dispositif de communication 4 peut comprendre un substrat 16 en plastique ou en composites laminés sur lequel sont collées la puce 6 et l'antenne 5.More precisely, this near field communication device 4 comprises an electronic chip 6 and at least one antenna 5. The chip 6 which is connected to said at least one antenna 5 comprises hardware and software elements. In this context, the hardware and / or software elements of the chip 6 of the device 4 comprise more precisely at least one microprocessor 13a cooperating with memory elements 13b. This chip 6 may be able to execute program code instructions for the implementation of a computer program. The memory elements 13b of this chip 6 can archive data relating to information on the timepiece 35 or on the carrier of this piece. Note that in an alternative, the communication device 4 may comprise a substrate 16 made of plastic or laminated composites on which the chip 6 is bonded and the antenna 5.

Dans cette pièce d'horlogerie 35, l'écran magnétique 8 encore appelé élément de blindage magnétique présente une perméabilité magnétique adaptée aux bandes de fréquences du champ magnétique généré par le dispositif de communication 4. Par exemple lorsque le dispositif de communication 4 fonctionne dans la bande des hautes fréquences HF, l'écran magnétique 8 présente une forte perméabilité magnétique initiale µ' avec µ' > 100 et de faibles pertes magnétiques µ" avec µ" < 7, et de préférence une perméabilité magnétique µ' de 150 et des pertes magnétiques µ" de 5.In this timepiece 35, the magnetic screen 8 also called magnetic shielding element has a magnetic permeability adapted to the frequency bands of the magnetic field generated by the communication device 4. For example when the communication device 4 operates in the high frequency band HF, the magnetic screen 8 has a high initial magnetic permeability μ 'with μ'> 100 and low magnetic losses μ "with μ" <7, and preferably a magnetic permeability μ 'of 150 and losses Magnetic μ "of 5.

Un tel écran magnétique 8 présente de préférence une résistivité électrique supérieure à 1000 KΩ/m et une épaisseur comprise entre 50 et 200 µm, et de préférence de 180 µm.Such a magnetic screen 8 preferably has an electrical resistivity of greater than 1000 KΩ / m and a thickness of between 50 and 200 μm, and preferably of 180 μm.

L'écran magnétique 8 peut être réalisé de préférence en matériau métallique comme la ferrite.The magnetic screen 8 may be preferably made of metallic material such as ferrite.

Cet écran magnétique 8 permet d'éviter une modification du champ magnétique émis ou reçu par le dispositif de communication, modification qui serait due à la présence de divers composantes métalliques 33 situées dans l'environnement immédiat du dispositif de communication 4 tels que le boîtier 20 ou encore le mouvement de la pièce 35. En effet, l'écran magnétique 8 est apte à pouvoir réduire l'influence négative que peuvent avoir ces composantes métalliques 33 sur les performances du dispositif de communication 4. Cette influence négative consisterait en l'atténuation du champ magnétique généré ou reçu par ce dispositif de communication 4.This magnetic screen 8 makes it possible to avoid a modification of the magnetic field emitted or received by the communication device, which modification would be due to the presence of various metallic components 33 located in the immediate environment of the communication device 4 such as the housing 20. or the movement of the piece 35. Indeed, the magnetic screen 8 is able to reduce the negative influence that can have these metal components 33 on the performance of the communication device 4. This negative influence would consist of the attenuation the magnetic field generated or received by this communication device 4.

Plus précisément, sur la figure 9A est illustrée une représentation schématique d'une pièce d'horlogerie 31 comprenant le dispositif de communication 4 agencé au niveau de la lunette 1 et/ou du cadran 2 et des composantes métalliques 33 telles que le boîtier 20 ou encore le mouvement. Cette pièce 31 est différente de celle de l'invention en ce qu'elle est dépourvue de l'écran magnétique 8. Dans cette configuration, lorsque le dispositif de communication 4 génère un champ magnétique caractérisé par des lignes de flux magnétique, ces dernières traversent des zones de ce ou ces composantes métalliques 33 se trouvant dans l'environnement immédiat du dispositif de communication 4. Les variations de ce champ magnétique qui traverse ces composantes métalliques 33 sont aptes à créer l'apparition de courants électriques appelés « courants de Foucault » dans ces zones. Une telle création de courants électriques dans ces zones a pour effet d'atténuer l'intensité de ce champ magnétique.More specifically, on the Figure 9A is illustrated a schematic representation of a timepiece 31 comprising the communication device 4 arranged at the bezel 1 and / or the dial 2 and metal components 33 such as the housing 20 or the movement. This piece 31 is different from that of the invention in that it is devoid of the magnetic screen 8. In this configuration, when the communication device 4 generates a magnetic field characterized by magnetic flux lines, the latter through areas of this or these metal components 33 located in the immediate environment of the communication device 4. The variations of this magnetic field that passes through these metal components 33 are able to create the appearance of electric currents called "eddy currents" in these areas. Such a creation of electric currents in these zones has the effect of attenuating the intensity of this magnetic field.

Sur la figure 9B, la pièce d'horlogerie 35 comprend en plus du dispositif de communication 4 et des composantes métalliques 33, l'écran magnétique 8 comme c'est le cas dans le présent mode de réalisation de l'invention. Cet écran magnétique 8 est agencé entre le dispositif de communication 4 et le ou les composantes métalliques 33 qui sont dans l'environnement immédiat de ce dispositif 4, selon différentes configurations décrites par la suite. Dans ces conditions, lorsque le dispositif de communication 4 génère un champ magnétique, ce dernier ne traverse pas les zones de ce ou ces composantes métalliques 33 se trouvant dans l'environnement immédiat du dispositif de communication 4. En effet, l'écran magnétique 8 est apte à canaliser ce champ magnétique en modifiant les lignes de flux magnétique résultant de ce champ de sorte que ces dernières ne traversent pas les composantes métalliques 33. Ainsi, ce ou ces composantes métalliques 33 sont alors isolées magnétiquement du champ magnétique généré par le dispositif de communication 4. Autrement dit, l'écran magnétique 8 est apte à séparer en deux zones la pièce d'horlogerie 35, une première zone comprenant les champs magnétiques générés par le dispositif de communication 4 et une deuxième zone qui n'est pas exposée à ces champs magnétiques grâce à l'action de l'écran magnétique 8.On the Figure 9B , the timepiece 35 further comprises the communication device 4 and metal components 33, the magnetic screen 8 as is the case in this embodiment of the invention. This magnetic screen 8 is arranged between the communication device 4 and the metal component or components 33 which are in the immediate environment of this device 4, according to various configurations described below. Under these conditions, when the communication device 4 generates a magnetic field, the latter does not cross the zones of this or these metal components 33 located in the immediate environment of the communication device 4. Indeed, the magnetic screen 8 is capable of channeling this magnetic field by modifying the magnetic flux lines resulting from this field so that the latter do not pass through the metal components 33. Thus, this or these metal components 33 are then magnetically isolated from the magnetic field generated by the device. 4. In other words, the magnetic screen 8 is able to separate the timepiece 35 into two zones, a first zone comprising the magnetic fields generated by the communication device 4 and a second zone that is not exposed. to these magnetic fields thanks to the action of the magnetic screen 8.

Ainsi, cet écran magnétique 8 permet d'améliorer l'efficacité et la sensibilité de la réception/transmission de signaux radio par l'antenne 5 du dispositif de communication 4 en isolant cette antenne 5 des composantes métalliques 33 comprises dans son environnement immédiat.Thus, this magnetic screen 8 makes it possible to improve the efficiency and the sensitivity of the reception / transmission of radio signals by the antenna 5 of the communication device 4 by isolating this antenna 5 from the metal components 33 included in its immediate environment.

On notera que cet écran magnétique 8 peut être souple ou rigide et comprendre au moins une couche, une plaque, un film ou un dépôt métallique de préférence en ferrite ou encore une résine polymère chargée en particules métalliques de ferrite. Un tel écran magnétique 8 est ainsi d'un faible encombrement.Note that this magnetic screen 8 may be flexible or rigid and include at least one layer, a plate, a film or a metal deposit preferably ferrite or a polymer resin loaded with ferrite metal particles. Such a magnetic screen 8 is thus of a small size.

Dans la pièce d'horlogerie 35, l'écran magnétique 8 est associé au dispositif de communication 4 en étant agencé dans la pièce 35 relativement à ce dispositif de communication 4, ou relativement à ce dispositif de communication 4 et à au moins une composante métallique 33 de ladite pièce 35 comprise dans l'environnement immédiat du dispositif de communication 4. Dans les différentes variantes des deux modes de réalisation décrits par la suite, l'écran magnétique 8 est associé au dispositif de communication 4 en étant agencé relativement à ce dernier de sorte à ce qu'il y ait un écart d'environ 0 à 2500 µm défini entre eux et/ou que cet écran magnétique 8 soit disposé entre le dispositif de communication 4 et au moins un composante électrique 33 comprise dans l'environnement immédiat dudit dispositif 4.In the timepiece 35, the magnetic screen 8 is associated with the communication device 4 while being arranged in the part 35 relative to this communication device 4, or relative to this communication device 4 and at least one metallic component 33 of said piece 35 included in the immediate environment of the communication device 4. In the various variants of the two embodiments described below, the magnetic screen 8 is associated with the communication device 4 being arranged relative to the latter so that there is a gap of approximately 0 to 2500 μm defined between them and / or that this magnetic screen 8 is disposed between the communication device 4 and at least one electrical component 33 included in the immediate environment said device 4.

On notera que lorsque l'écart entre l'écran magnétique 8 et le dispositif de communication 4 est sensiblement nul, alors l'écran magnétique 8 peut être associé au dispositif de communication 4 en réalisant l'écran magnétique par une technique d'impression, de sérigraphie, de collage ou encore de vaporisation d'une peinture métallique sur un support compris ou rapporté au dispositif de communication 4. On choisit alors un support présentant d'excellentes propriétés d'isolation électrique. Ce support peut être une couche de matériau, un film, un ruban, etc.... Dans cette configuration, ce support peut être localisé uniquement au niveau de l'antenne 5 du dispositif de communication 4 ou encore au niveau de l'antenne 5 et de la puce 6.It will be noted that when the distance between the magnetic screen 8 and the communication device 4 is substantially zero, then the magnetic screen 8 can be associated with the communication device 4 by producing the magnetic screen by a printing technique, screen printing, gluing or even vaporization of a metallic paint on a support included or attached to the communication device 4. A support having excellent properties of electrical insulation is then chosen. This support can be a layer of material, a film, a ribbon, etc. In this configuration, this support can be located only at the antenna 5 of the communication device 4 or at the antenna level. 5 and the chip 6.

A titre d'exemple, cet écran magnétique 8 est associé au dispositif de communication 4 en étant agencé dans la pièce d'horlogerie 35 en-dessous de ce dispositif de communication 4 c'est-à-dire entre le mouvement constituant une composante métallique 33 de ladite pièce 35 et ce dispositif de communication 4. Dans cette configuration, l'écran magnétique 8 est associé avec le dispositif de communication 4 en n'étant pas en contact direct avec l'antenne 5 du dispositif de communication 4 mais en pouvant être en contact avec la puce 6.By way of example, this magnetic screen 8 is associated with the communication device 4 by being arranged in the timepiece 35 below this communication device 4, that is to say between the movement constituting a metallic component. 33 of said piece 35 and this communication device 4. In this configuration, the magnetic screen 8 is associated with the communication device 4 by not being in direct contact with the antenna 5 of the communication device 4 but may be in contact with the chip 6.

Ainsi que nous l'avons évoqué précédemment, dans le premier mode de réalisation de la pièce d'horlogerie 35, le dispositif de communication 4 est agencé au niveau du cadran 1. Ce premier mode de réalisation comprend quatre variantes de cadran 1 au niveau desquelles est agencé le dispositif de communication 4. Un tel cadran 1 est en exécution monobloc. Il est réalisé de préférence en matière rigide permettant d'assurer une bonne tenue, et un aspect correct de l'affichage.

These first and second inner faces 30a, 30b comprise connecting elements. The connecting elements of each of these first and second faces 30a, 30b may have complementary shapes to ensure a mechanical connection between these two components 17a, 17b when they are assembled with each other.

Dans cette variante, la deuxième face intérieure 30b de la deuxième composante 17b comprend un logement 18 dans lequel le dispositif de communication 4 peut être agencé. Ce logement 18 forme une gorge ou encore une rainure annulaire s'étendant dans la deuxième face intérieure 30b de la deuxième composante 17b de la lunette 2. Ce logement 18 a une section transversale pouvant avoir la forme d'un « U ». Un tel logement 18 comprend une paroi de fond 19a et une paroi latérale 19b ayant chacune une surface sensiblement plane, la paroi latérale 19b étant de préférence perpendiculaire à la paroi de fond 19a.In this variant, the second inner face 30b of the second component 17b comprises a housing 18 in which the communication device 4 can be arranged. This housing 18 forms a groove or an annular groove extending in the second inner face 30b of the second component 17b of the bezel 2.

Such a housing 18 comprises a bottom wall 19a and a side wall 19b each having a substantially flat surface, the side wall 19b preferably being perpendicular to the bottom wall 19a.

La paroi latérale 19b de ce logement 18 forme avec une partie 29 de la deuxième face intérieure 30b ne constituant pas ce logement 18, un bord 28 qui définit une ouverture du logement 18.The side wall 19b of this housing 18 forms with a portion 29 of the second inner face 30b not constituting this housing 18, an edge 28 which defines an opening of the housing 18.

Dans cette variante, l'ouverture de ce logement 18 est définie sur environ 30 à 70% de la deuxième face intérieure 30b, et de préférence sur 50% de cette face. Ce logement 18 présente une profondeur P3 d'environ 200 à 2500 µm, de préférence 1000 µm.In this variant, the opening of this housing 18 is defined on about 30 to 70% of the second inner face 30b, and preferably on 50% of this face. This housing 18 has a depth P3 of about 200 to 2500 μm, preferably 1000 μm.

Dans cette variante, lorsque le dispositif de communication 4 est associé avec l'écran magnétique 8, ce dernier est agencé dans le logement 18. Cet écran magnétique 8 peut correspondre à une couche, un film ou un dépôt métallique qui est appliqué sur la paroi de fond 19a et/ou la paroi latérale 19b du logement 18. L'application de cet écran magnétique 8 dans le logement 18 peut être réalisée selon une technique d'impression, de sérigraphie ou encore de vaporisation d'une peinture métallisée.In this variant, when the communication device 4 is associated with the magnetic screen 8, the latter is arranged in the housing 18. This magnetic screen 8 may correspond to a layer, a film or a metal deposit which is applied to the wall bottom 19a and / or the side wall 19b of the housing 18. The application of this magnetic screen 8 in the housing 18 may be performed by a printing technique, screen printing or even vaporization of a metallized paint.

Le dispositif de communication 4 est ensuite disposé dans le logement 18 au-dessus de l'écran magnétique 8. Plus précisément la puce 6 et l'antenne 5 peuvent être fixées à au moins un élément de support compris sur la paroi de fond 19a et/ou la paroi latérale 19b par collage ou encore par emboîtage de sorte que l'antenne 5 du dispositif de communication 4 ne soit pas en contact avec l'écran magnétique 8. L'élément de support peut correspondre à au moins un bras de fixation ou encore à une couche de matière. Cette couche de matière peut couvrir tout ou partie de l'écran magnétique 8 agencé dans le logement 18, et présenter des propriétés d'isolation électrique. Alternativement, le dispositif de communication 4 peut être fixé sur une zone de liaison définie sur la première face intérieure 30a de la première composante 17a. Cette zone de liaison est située en regard du logement 18 lorsque les première et deuxième composantes 17a, 17b sont assemblées l'une avec l'autre.The communication device 4 is then placed in the housing 18 above the magnetic screen 8. More precisely, the chip 6 and the antenna 5 can be attached to at least one support element included on the bottom wall 19a and / or the side wall 19b by gluing or by fitting so that the antenna 5 of the communication device 4 is not in contact with the magnetic screen 8. The support member may correspond to at least one attachment arm or a layer of matter. This layer of material may cover all or part of the magnetic screen 8 arranged in the housing 18, and have electrical insulation properties. Alternatively, the communication device 4 can be fixed on a bonding zone defined on the first inner face 30a of the first component 17a. This connection zone is located opposite the housing 18 when the first and second components 17a, 17b are assembled with each other.

Dans cette variante de la lunette 2, l'alternative du dispositif de communication 4 comprenant le substrat 16 en plastique ou en composites laminés sur lequel sont collées la puce et l'antenne 5, peut également être agencé dans ce logement 18 selon les mêmes principes évoqués précédemment pour cette deuxième variante.In this variant of the telescope 2, the alternative of the communication device 4 comprising the substrate 16 made of plastic or laminated composites on which the chip and the antenna 5 are glued, can also be arranged in this housing 18 according to the same principles. previously mentioned for this second variant.

Dans cette deuxième variante, l'ouverture de ce logement 18 est alors obturée lorsque la première composante 17a est assemblée avec la deuxième composante 17b pour former la lunette 2.In this second variant, the opening of this housing 18 is then closed when the first component 17a is assembled with the second component 17b to form the telescope 2.

Dans ces deux modes de réalisation de l'invention, le dispositif de communication 4 et l'écran magnétique 8 peuvent être compris dans un module en étant par exemple surmoulés dans une même pièce en polymère. Un tel module peut alors être agencé dans le cadran 1 et la lunette 2 selon les différentes variantes décrites précédemment. L'agencement de ce module dans ces différentes variantes est de préférence réalisé de manière à ce que l'antenne 5 rayonne de manière optimale en direction du périphérique associé avec lequel la pièce d'horlogerie 35 est apte à échanger des données.In these two embodiments of the invention, the communication device 4 and the magnetic screen 8 may be included in a module being for example overmolded in the same polymer part. Such a module can then be arranged in the dial 1 and the bezel 2 according to the different variants described above. The arrangement of this module in these different variants is preferably made so that the antenna 5 radiates optimally towards the associated device with which the timepiece 35 is able to exchange data.

Dans cette pièce d'horlogerie 35, le boîtier 20 est adapté pour optimiser/maximiser les performances du dispositif de communication 4 agencé au niveau de la lunette 2 ou du cadran 1. En effet, ce boîtier 20 peut être réalisé en tout ou partie en une matière présentant des propriétés de conductivité électrique nulles telle que le saphir synthétique, la céramique ou encore en un polymère injecté ou moulé tel que le polyamide-nylon PA12, le polycarbonate PC ou encore le polyphenylsulfone PPSu. Ainsi, le boîtier 20 peut être réalisé intégralement en cette matière. Mais le boîtier 20 peut alternativement être réalisé que partiellement en cette matière en ayant qu'une partie de ces composants conçue en cette matière par exemple les composants qui sont situés au-dessus du cadran 1 comme par exemple une partie de la carrure située au-dessus du niveau du cadran 1 et de la lunette 2.In this timepiece 35, the housing 20 is adapted to optimize / maximize the performance of the communication device 4 arranged at the level of the bezel 2 or the dial 1. In fact, this housing 20 can be made in whole or in part. a material having properties of zero electrical conductivity such as synthetic sapphire, ceramic or an injected or molded polymer such as polyamide-nylon PA12, polycarbonate PC or polyphenylsulfone PPSu. Thus, the housing 20 can be made integrally in this matter. But the housing 20 may alternatively be realized only partially in this matter having a part of these components designed in this matter for example the components that are located above the dial 1 as for example a part of the middle part located above the level of the dial 1 and the telescope 2.

Ainsi que nous l'avons vu précédemment, le cadran 1, la lunette 2 voire tout ou partie du boîtier 20 peuvent être réalisés dans une matière présentant des propriétés de conductivité électrique nulles. La non-conductivité électrique d'une telle matière est quantifiée par sa résistivité qui caractérise sa capacité à s'opposer à la circulation du courant électrique. La résistivité de cette matière est supérieure à 1012 Ω/cm, et est de préférence supérieure à 1013 Ω/cm.As we have seen previously, the dial 1, the bezel 2 or all or part of the housing 20 may be made of a material having properties of zero electrical conductivity. The electrical non-conductivity of such a material is quantified by its resistivity which characterizes its ability to oppose the flow of electric current. The resistivity of this material is greater than 10 12 Ω / cm, and is preferably greater than 10 13 Ω / cm.

On notera que l'agencement du dispositif de communication dans des parties supérieures de la pièce comme le cadran 1 et la lunette 2 permet de limiter les effets perturbateurs pouvant résulter du poignet du porteur de ladite pièce 35.Note that the arrangement of the communication device in upper parts of the room as the dial 1 and the bezel 2 limits the disruptive effects that may result from the wrist of the wearer of said piece 35.

La présente invention n'est pas limitée aux modes de réalisation qui ont été explicitement décrits, mais elle en inclut les diverses variantes et généralisations contenues dans le domaine des revendications ci-après.The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations thereof within the scope of the claims below.
