Abstract
A sealing device (1) for a watch crown that includes a cover (2) possessing an annular part (3) that fits and rests on the periphery of a cabochon (4) of a watch crown (5) against a seal (6). Said cover (2), which is articulated on one of the shoulders (7) protecting the crown (5) of a watchcase (8) has, at its end, a closure lug (9). The latter is designed to receive a buckle (10) integral with a fastening arm (12). This fastening arm (12) makes it possible for the cover (2) to exert sufficient pressure on said seal (6) by means of a simple lever effect when the end of the fastening arm (12) is inserted into a receptacle (15).
