A flexible device includes a casing; a functional element mounted on the casing; and a flexible assembly which is deformable and mounted on the casing, in which a deformation of the flexible assembly drives the flexible device to deform accordingly.

An attachment link for a watch band is arranged to attach the band to a watch case between the horns. A first end of the attachment link is fixed to a watch band strand and the second end of the attachment link is fixed to the case with a bar. The link is between the horns and against the case. The attachment link includes a device for blocking pivoting in order to firmly hold the attachment link between the horns.

A jewelry item is provided to include a ring-shaped spring and a ring-shaped chain. The ring-shaped chain has a plurality of chain links, each of which is slidably attached to the ring-shaped spring. Each chain link has a plate with a first surface facing the spring and a second surface opposite to the first surface. Each chain link further has a seat and a hook opposite to each other. The hook is inserted into a seat of a subsequent chain link so as to lock the chain links to each other while allowing the chain links to reversibly slide from a compressed position to an expanded position with respect to each other.

A wearing band including plural first zigzag springs and plural second zigzag springs. The plural first zigzag springs have axial directions in a length direction of a band body that is formed in a belt shape or a ring shape. The plural first zigzag springs are arrayed in the length direction and a width direction of the band body so as to form a section stretching and contracting in the length direction of the band body. The plural second zigzag springs have axial directions in the width direction of the band body and are arrayed in the length direction and the width direction of the band body so as to form a section stretching and contracting in the width direction of the band body. The plural second zigzag springs have a spring constant different to a spring constant of the plural first zigzag springs.

A flexible band wearable electronic device includes a plurality of rigid links. The flexible band wearable electronic device also includes a number of pivot joints coupling the plurality of rigid links together. The flexible band wearable electronic device further includes a first electronic device on a first of the plurality of rigid links, and a second electronic device on a second of the plurality of rigid links. The flexible band wearable electronic device still further includes an electrical communication pathway between first electronic device and the second electronic device and through at least a portion of one of the number of pivot joints.
