摘要： A super hard wristwatch case, where fractures, cracks and/or breaks are prevented from being produced in leg portions of a case body on installation and removal of spring rods for installing a wristwatch band, is disclosed. This is achieved by a simple modification to the structure of the wristwatch case. The super hard wristwatch case is provided with a shock-resistant metallic back cover (2) having left/right pairs of projection pieces (20a, 20b, 21a, 21b) provided on a surface thereof which faces a case body (1), the projection pieces being located so as to be opposed to inner wall faces of the leg portions (11a, 11b, 12a, 12b), the projection pieces being formed with fixing holes (22a, 22b, 23a, 23b) for spring rods (3) in regions thereof that are adjacent tips of the projection pieces, the projection pieces being fitted and fixed in the inner wall faces of the leg portions. The spring rods (3) are bridged and engaged between the projection pieces (20a, 20b, 21a, 21b).
