  • Patent number: 4935910
    Abstract: In fitting of a band to a wristwatch case; in order to minimize the gap at the area of fitting of these members, or pretend that a middle that constitutes the watch case is formed integral with the band and also to prevent excessive pivoting of the band relative to the watch case when the user wears the wristwatch, a recess for receiving the end portion of the band is formed in a part of the middle which is contiguous with each fitting portion where the band is fitted to the middle, thereby limiting the pivoting of the first link of the band by the inner wall of the recess. In addition, a projection is provided in the center of each of the fitting portions formed on the watch case to limit the pivoting of the second link of the band by the distal end of the projection.
