Abstract
A wristwatch case includes a caseband (12) which receives a movement (2) surmounted by a dial (3). A crystal (5) and a back cover (6) are secured to the caseband as well as first (7) and second (8) bracelet strands. The back cover entirely covers over the underside of the caseband and includes first (9) and second (10) integrally formed wings. Such wings cover over entirely the outer sides (11) exhibited by the caseband and which are found situated between the bracelet strands. The back cover is preferably made of ceramic material.
