CA 2537187

The inventive metal case watch comprises an electronic reading in information module (14) which is arranged in an external cavity (13) of the bottom of a case (3). Said module can communicate with an information reader and/or recorder (35) by radio transmitted signals and consists of a socket (15) on which an integrated circuit chip (24) provided with at least two connection terminals (26) and a coil (23) in the form of a transmitting/receiving antenna is mounted. Said coil consists of an electrically conducting wire whose two ends (29) are connected to said connection terminals of the integrated circuit chip, respectively. The coil embraces a space in which the chip is arranged. The cap-shaped socket of the electronic module (14) is used as a metallic element for conducting a magnetic flux in order to magnetically insulate the module body from the metal case during information transmission between the reader and/or recorder of said module. The socket (15) of the module (14) can be covered by a protective lid (28).

La montre à boîtier métallique comprend un module électronique (14) pour la mémorisation d'informations qui est monté dans une cavité extérieure (Il 3) du fond d'un boîtier (3). Ce module peut communiquer par des signaux radio~diffusés avec un appareil de lecture et/ou d'écriture (35) desdites informations. Le module comprend un socle (Il 5) sur lequel sont montés une puce de circuit intégré (24) présentant au moins deux bornes de connexion (26) et une bobine (23) servant d'antenne d'émission et/ou de réception. Cette bobine est constituée par un fil électriquement conducteur ayant deux extrémités (29) reliées respectivement aux dites bornes de connexion de ladite puce de circuit intégré. La bobine entoure un espace dans lequel est placée ladite puce. Le socle du module électronique (14) sous forme de cuvette est un élément métallique conducteur de flux magnétique pour isoler magnétiquement la bobine du module du boîtier métallique lors d'une communication d'informations entre un appareil de lecture et/ou d'écriture et ledit module. Le socle (15) du module (14) peut être recouvert par un couvercle de protection (28).
