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).

摘要： [PROBLEMS] To provide a hard wrist watch case having a structure where cracking or chipping incident to attachment/detachment of a spring rod for supporting a watch band does not take place at the leg of a case frame body by enhancing decorativeness and rigidity of the hard wrist watch case through simple alteration of configuration, and having a back lid fixing structure where brazing of a screw bush to the case frame body is not required. [MEANS FOR SOLVING PROBLEMS] An impact resistant metallic decoration component provided with spring rod stop holes at the opposite ends and a screw latch component like a projection piece are fitted, respectively, to a groove and a cavity provided in the side faces of the case frame body on the three o'clock side and the nine o'clock side, and buried in through holes provided at the leg of the case frame body such that the stop hole of the spring rod is exposed to the inner wall face of the band fixing space at the leg. When a back lid is fixed, a screw for latching the back lid is screwed into the screw hole of the screw latch component arranged at the cavity of the case frame body thus securing the back lid to the case frame body. Similarly, the spring rod is stretched between the stop holes of the decoration component when a wrist bandis fixed.
