Abstract (en)
[origin: EP0556155A1] This device includes a crown (13) having a central cavity (12) and an annular cavity (15), in the back of which a groove (18) is accommodated. The lateral external face of the annular cavity (15) has a threading (17) intended to be screwed onto a threading made on the external lateral face (8) of an outside part of a tube (4) screwed into a watchcase calibre (1). A seal (19) of injected thermoplastic elastomer is arranged inside the annular cavity (15). This seal includes two portions (19a, 19b) of like external diameters but of unlike inside diameters, the portion of larger outside diameter (19a) engaging into the groove (18) and the portion (19b) of smaller inside diameter being that acted upon by the tube (4) in the screwed-home position of the crown. <IMAGE>
