Timepiece with tactile control comprising an anti-fog device

A timepiece comprising a case forming an electrical mass, said case being closed by a back and by a protective glass, said timepiece comprising a tactile control device connected to an electronic unit configured to execute at least one predetermined function of said timepiece under the action of the tactile control device, said tactile control device comprising at least one capacitive sensor comprising a first armature formed by a transparent conductive electrode, formed at least on a portion of an internal face of the protective glass, and a second armature formed selectively by the positioning of the finger of the wearer of said timepiece on an external face of the protective glass;

• said transparent conductive electrode being electrically connected to said electronic unit by a first electrical conductor;
• wherein the timepiece comprises an anti-fog device of said protective glass formed in part by said transparent conductive electrode and by a second electrical conductor connecting said transparent conductive electrode to said electronic unit in a closed circuit, said electronic unit comprising an electric current management module configured to generate a controlled electric current in the closed circuit enabling said transparent conductive electrode to heat up by Joule effect.
