Smart watch comprising a common-ground device for a horological movement

Abstract

A smart watch (1) including a case (100) having a middle (110), a horological movement (10) housed in the middle (110) and having a processing unit (13) and a communication module (12) electrically connected to electrical conductors (18) in the horological movement (10). The smart watch (1) also includes a common-ground device formed by a conductive resilient ring (200) having an annular body (205) with a central axis (Z), fastening tabs (210) carried by the annular body (205) and cooperating with the middle (110) to form a bayonet locking system (300) by the rotation of the conductive resilient ring (200) relative to the middle (110), about the central axis (Z), between an insertion position and a locked position. The conductive resilient ring (200) includes conductive lugs (250) in electrical contact with the electrical conductors (18) when the conductive resilient ring (200) is in the locked position in the middle (110).
