Abstract
Abstract A timepiece which includes a case (2), a horometric movement (4) housed within the case (2) and means for broadcasting an electromagnetic signal including electronic means (12) for furnishing the signal and at least one broadcasting antenna (14) coupled to the electronic means (12). Such timepiece is characterized in that the antenna (14) is arranged on a first face (20a) of a support plate (20) of basically planar form arranged in the interior of the case (2), such antenna (14) being constituted by a thin metallic layer deposited on the face (20a) of the support plate (20). This timepiece is applicable to the control of an arrangement, for example for latching and unlatching, of a door in particular.
