Watertight wrist-watch case

摘要

The case has a protective cover in which a plane peripheral surface extending on an edge of an internal face of a glass (3) in sapphire, contacts with a homologous support surface of a lateral wall (2) of the cover. A portion of the support surface forms a width of a section of a structure (SR) resistant to compression at parallel lateral faces. The support surface extends until a base (1) of the cover and encircles a portion of the wall and the base, which is made of ceramic. A watertight and fixation unit is provided for elements of the cover. The wall and the base form a single part.
