Rotating-bezel system comprising a ceramic rotating bezel

A rotating-bezel system configured to be mounted for rotation on a middle of a watch case inside which a horological movement is housed, the rotating-bezel system comprising:

• a ceramic rotating bezel;
• an annular ring configured to cooperate with an element angularly secured to the middle;
• an annular joint for connection between the rotating bezel and the annular ring, the annular ring being placed in the rotating bezel;
• and
• at least one locking element for locking the annular ring on the rotating bezel, said at least one locking element being configured to lock any relative rotation between the annular ring and the bezel and thus to angularly secure the assembly formed by the ring and the bezel,
• wherein a bottom face of the annular ring includes a reception opening for receiving the at least one locking element,
• wherein a top part of the annular ring in line with the reception opening includes a shoulder defining an internal recess,
• wherein an internal periphery of the rotating bezel includes an internal groove,
• wherein the at least one locking element has a body elongate in a longitudinal extension direction, the body having a substantially L-shaped cross section with a first part forming a main arm of the L-shape and a second part forming a foot of the L-shape, and
• wherein the second part is received in the internal groove of the rotating bezel and a top surface of the second part abuts a bottom surface of the shoulder of the annular ring.
