Abstract

The watch case of this invention includes a caseband (2) made from sintered material and a back cover (10) secured to the caseband by means of at least two pins (12). Each pin passes through a first hole (14) provided in a first projection (16) formed in the caseband and two second holes (13, 15) provided respectively in two second projections (17, 18) formed in the back cover, said second projections being arranged respectively on either side of said first projection. Each pin being axially retained in its holes by the elastic effect provided by the seal when the caseband lies on the back cover.
