Abstract: 본 발명은 내부에 시계 무브먼트가 수용되는 와치 케이스의 미들에 회전 장착되도록 되어 있는 회전-베젤 시스템에 관한 것으로, 이 시스템은 세라믹 회전 베젤, 상기 미들에 각지게 고정된 요소와 협력작동하도록 되어 있는 환형 링, 및 상기 회전 베젤과 상기 환형 링 사이의 연결을 위한 환형 조인트를 포함하고, 상기 환형 링은 상기 회전 베젤에 배치된다.     본 발명에 따르면, 상기 시스템은 상기 회전 베젤상에서 상기 환형 링을 잠금하기 위한 적어도 하나의 잠금 요소를 더 포함하고, 상기 적어도 하나의 잠금 요소는 상기 환형 링과 상기 베젤 사이의 임의의 상대 회전을 잠금하도록 그리고 그에 따라 상기 환형 링과 상기 베젤에 의해 형성된 어셈블리를 각지게 고정하도록 구성된다.
