Abstract:
The invention concerns a device for fixing a back (1) on a watchcase middle (12), characterized in that it comprises an intermediate element (10) whereto the back (1) is linked, said intermediate element (10) being screwed on the watch middle (12), means being provided to enable the intermediate element (10) to be driven in rotation by the back (1) until it reaches a locking position on the middle (12), the back (1) being further capable of being pivoted relative to the intermediate element (10) without being unscrewed to be aligned with the axis 12H-6H of the watch.
Abstract:
The invention relates to a control device for a watch case comprising a case middle delimiting an inner volume in which a movement is located, with the device comprising a mobile-mounted rotary bezel on the case middle and a transmission component comprising: a mobile-mounted rotating stem in a hole traversing the case middle, with a first cam located within the inner volume of the securely mounted case middle rotating at the tip of the stem, and acting in unison with a control lever mounted on the movement when the transmission component turns and a second cam located on the outside of the volume, securely mounted and rotating with the other extremity of the stem, and comprising at least one support surface. The case middle comprises yet another contact surface designed to act in unison with the support surface when the case middle turns, so that it includes the transmission component in the rotation. The control device also contains a return spring acting on the case middle.
Abstract:
The invention relates to watches, generally wristwatches, with cases comprising built-in electronic information-storage units. The aforementioned units consist of an integrated circuit chip which is connected to an antenna comprising a coil and can communicate by means of broadcast signals with a read and/or write device. The read and/or write device is used at least to read the information contained in a memory element of the integrated circuit chip and often to delete or modify at least one part of said information and to add other information. In order to eliminate the inconveniences associated with known watches of said type in which the information-storage units are located inside the case (more complicated production or novel design of case, increased case volume) or to diminish the significance of said inconveniences (attenuation and/or deformation of signals emitted or received by the coil), the electronic unit (14) of the inventive watch is housed for the most part at least in a cavity (13) which is open to the external environment and which is disposed in the base (3) of the case (1).
