The watch with a metallic case including an electronic module for storing data, which is mounted in an external cavity in the back cover of a case. The module can communicate via broadcast signals with a read and/or write apparatus for said data. The module includes a base on which are mounted an integrated circuit chip having at least two bumps and a coil acting as a transmission and/or reception antenna. The coil is formed by an electrically conductive wire having two ends respectively connected to said bumps of said integrated circuit chip. The coil surrounds a space in which said chip is placed. The dome-shaped base of the electronic module is a metallic element that conducts magnetic flux to insulate the module coil magnetically from the metallic case during data communication between a read/write apparatus and said module. The base of the module can be covered by a protective cover.
