ABSTRACT:
There is disclosed a wristwatch (21) including a middle part (22) defining a middle plane (Y), conductive means (35, 36) for attaching the wristband (32) to the middle part, a radio-frequency module (27) arranged inside the middle part and connected, on the one hand, to a ground plane and, on the other hand, to a radiating element, insulated from each other and forming an antenna. The ground plane includes at least one conductive surface portion (37) of the wristband connected to the wristband attaching means and the middle part which is conductive, the latter being connected from the inside to the radio-frequency module. The radiating element includes a first conductive surface element (25) arranged in a substantially parallel plane to the middle plane defined by the middle part.
