Abstract (en)
The control for a watch comprises a screw threaded crown (6) attached to a shaft (8) extending into the body of the watch. A tube (3) attached to the watch casing provides an externally threaded portion (5) which co-operates with the thread of the crown. The crown thread may be a multiple thread. The control for a watch comprises a screw threaded crown (6) attached to a shaft (8) extending into the body of the watch. The crown has an annular cavity on the side facing the watch body, defining an annular wall (12) which extends towards the watch, parallel to the axis of rotation (D) the shaft (8). The annular wall (12) has an internal thread (13). A tube (3) which is solidly attached to the watch casing projects around the shaft, and provided an externally threaded portion (5) which co-operates with the thread of the crown. A sealing ring (15) may be accommodated in the base of the annular cavity, pressing against the top of the tube in order to form a seal when the crown is screwed into place. The crown thread may be a multiple thread.
