A wristwatch case has a side wall over which an outer ring is removably engaged and held by two spring members each having a middle part forming a bracelet loop and curved extremities engaging in facing grooves of the case and wall. An outer terminal part of each extremity normally engages in the groove of the ring but, for fitting or removal of the ring, can be compressed into a groove of the case by an inclined surface on the ring. |
