Title:
WATCH COMPRISING AN ELECTRONIC INFORMATION-STORAGE UNIT IN THE BASE OF THE CASE THEREOF
Document Type and Number:
WIPO Patent Application WO2004025381
Kind Code:
A3
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).
