Abstract
Sub-assembly of external parts for a watch, comprising a water-resistant joint between a first and a second component, which are screwed, one on the other, the first component supports a first inclined toothing, which cooperates with a second inclined toothing of the second component, the first component or second component, or a second ring interposed between them comprises a zone which is elastically deformable under the action of a relative rotation between the first and the second component which is caused by an external force, and the deformation range of which allows compression of the elastically deformable zone allowing clearance of the teeth tips during the relative rotation and a release of this zone, allowing return to cooperation of the tips and the hollows of the teeth in a new relative angular position.
