Zusammenfassung:The metal ring includes a stepped structure retaining the elastomer seal material between the major casing components. The watch casing is closed by a cover glass (3) and a base (2) which fit with a casing ring (6) to define a space (9) to house the movement (29). A metallic centre component (30) includes an external wall with a stepped external structure which is complementary to the internal structure of the cover (20). The cover is solidly attached to the centre (30) by means of two screws (14, 16), retain tabs (15,17) lodged in radial hollows formed within a vertical wall of the cover. An elastomer joint (12) is disposed between two horizontal surfaces which form part of the stepped structure. The thickness of the elastomer joint is sufficient to ensure a degree of play between the facing surfaces of the base and the lower surface of the cover, and between the vertical wall of the metallic centre and the wall of the cover which joins the base. Boîte de montre (1) fermée par une glace (3) et un fond (2) délimitant avec un cercle d'emboîtage (6), un espace (9) pour loger au moins un mouvement (29), comprenant un centre métallique (30) dont la paroi externe a une structure en escaliers (31, 31a, 32, 32a, 33) complémentaire de la structure interne (21, 21a, 22, 22a, 23, 23a) de la coiffe (20) rendue solidaire dudit centre (30) au moyen d'au moins deux vis (14, 16) le traversant à travers des perçages (34, 36) pour serrer des brides (15, 17) logées dans des creusures radiales (25, 27) formées dans une paroi (21a) verticale de la coiffe (20) en comprimant un joint élastomère (12), disposé entre deux surfaces horizontales (22, 32) des structures en escalier, et dont l'épaisseur est suffisante pour ménager des jeux (41, 41a) au moins entre des surfaces en regard respectivement du fond (2) et de la base (21) de la coiffe (20), et de la paroi verticale (31a) du centre (30) et la paroi (21a) de la coiffe (20) rejoignant la base (21).
