Abstract (en)
[origin: EP0603721A1] The invention relates to a timepiece which includes a case (2), a clockwork movement (4) housed inside the case (2) and means for transmitting an electromagnetic signal including electronic means (12) of delivering the signal and at least one transmitting antenna (14) coupled to the electronic means (12). This timepiece is characterised in that the antenna (14) is accommodated on a first face (20a) of a support plate (20) of essentially planar shape arranged inside the case (2), this antenna (14) consisting of a thin metallic layer deposited on the face (20a) of the support plate (20). This timepiece applies to the control of a device, for example for locking and unlocking, in particular, a door. <IMAGE>
