Abstract: The invention relates to a watch housing comprising a body made in two parts (2, 3), connected one to the other. The one of the two parts (2) guarantees the function of a watch whilst the second part (3), connected to the bracelet, comprises means for attachment of an interchangeable module (M). Said module (M) is extended by an elastic tongue (20) and security means are provided to ensure that the tongue (20) is supported on the first part (2) whilst subjecting the above to a permanent force maintaining the same in the open position.

Abstract: A wristwatch with a usable dial, fitted with keys, includes an electronic device to form a multifunctional wrist worn device. The structure of the wristwatch is such that there is enough space to regularly actuate each key with a finger. The part of the multifunctional device providing the time can be shifted to free up the device's body. In particular, this device is characterized by the fact that the device's body, freed up in this way by the shift of the watch, contains, on its periphery, a number of keys that make it possible to easily actuate the electronic device with a finger. This simple device makes it possible to cover and to mask the electronic device's keys when the latter are not being used, the device according to the invention then having the general appearance of a wristwatch.

Abstract: A wristwatch includes an electronic device to form a multifunctional wrist worn device. The watch portion of the wristwatch can be shifted into a position that exposes the electronic device (e.g., telephone) so that the user can operate the electronic device. The keys are located on the periphery of the watch body. A display can be mounted on the back side of the watch portion so that when the watch portion is in the second position, the display is visible to the user.
