Abstract

This device includes a groove (6) made in the internal wall of the counterbore (2) of the calibre (1) providing passage to the pipe of the winding crown (4). A seal (8) is placed in this groove (6). The internal diameter of the seal (8) is smaller than the external diameter of the pipe of the winding crown and is thus compressed between this pipe and the wall of the groove (6). The groove is bounded on the outside by a ring (7) of the same precious metal as the case. <IMAGE>
