The invention includes a device for securing a back cover on a middle part of a watchcase, characterized in that it includes an intermediate element to which the back cover is connected, the intermediate element being screwed onto the middle part of the watch, an element arranged to allow the back cover to drive the intermediate element in rotation until the latter reaches a locked position on the middle part, the back cover also being pivotable relative to the intermediate element without the latter being unscrewed for alignment with the 12 o'clock-6 o'clock axis of the watch.

Device for securing a back cover to the middle part of a watch

The invention concerns a bracelet or wristband of adjustable length, including:

Bracelet or wristband of adjustable length

The wristband with a clasp () includes electrical connection means () for connection to at least one electric or electronic component (). These electrical connection means include an electric connector () arranged in one part of the clasp connected to one end of a wristband strand. The connector is of the universal serial bus type so as to be able to be connected, when the clasp is in the open position, to a connector of complementary shape of an electric apparatus, such as a computer station for carrying out energy and/or data transmission with the electric or electronic component. The connector is protected by a fastening piece () and bellows () when the clasp is in the closed position.

Bracelet with clip comprising electrical connection means

The invention relates to watches, generally wristwatches, whose cases incorporate electronic modules for storing information that comprise an integrated circuit connected to an antenna consisting of a coil and are able to communicate by radio signals with a reading and/or writing device adapted at least to read the information contained in a memory of the integrated circuit and often also adapted to delete or modify at least some of that information and to add other information. To eliminate the drawbacks of prior art watches in which the module is inside the case (complicated fabrication or new design of the watch, increased volume thereof) or to reduce the importance of those drawbacks (attenuation and/or distortion of the signals sent and received by the coil), in the watch of the invention the electronic module () is housed at least for the most part in a cavity () in the back () of the case () open towards the outside.
