A portable object includes a case having a middle, a bracelet, and an attachment system for removably securing each end of the bracelet to the middle. The middle includes two longitudinal cavities to form a slide bar. Each end of the bracelet includes a fastening head that cooperates, by sliding, with one of the longitudinal cavities to form the attachment system. The fastening head includes an end flange made of a viscoelastic material. The attachment system includes a viscoelastic fitting for locking axial movement of the fastening head inside the longitudinal cavity by the viscoelastic response of the end flange. The viscoelastic fitting is formed by cooperation of a rigid locking protrusion in each longitudinal cavity to deform the end flange upon insertion of the bracelet. The locking protrusion fits inside a recess made in the end flange to lock the axial movement of the fastening head.

A detector includes an elastic conductive blade having first and second ends and a central portion therebetween, with the blade being designed to be driven axially by a control rod to occupy three distinct positions between the pulled position and the end position of the rod: a pulled position, an end position, and an intermediate position. Two electrical contacts are designed to detect the end position and the pulled position of the rod, respectively. The blade is designed to pivot at its first end when the rod passes from the intermediate position to the pulled position, or vice versa. The blade is designed to undergo elastic deformation when the rod passes between the intermediate position and the end position so as to participate substantially in a restoring force of the rod toward the intermediate position when the axial activating force applied to the rod by a user is released.

Control device equipped with a module for detecting the axial position of its rod, and timepiece comprising such a control device

A watch intended to be removably mounted on a support, including a watch case and an independent removable attachment device arranged to retain the watch case in an opening provided in the support, the watch case including an upper portion, on the dial side, and a lower portion including a back cover, the lower portion being arranged to be housed inside the opening in the support and being of smaller dimensions than those of the upper portion to form a flat peripheral shoulder. The attachment device includes a flange having a central opening arranged to receive the lower portion of the watch case and an inner rim delimiting the central opening, the inner rim being arranged to be housed inside the opening in the support. The inner rim includes a locking device for locking the attachment device on the lower portion of the watch case.

A timepiece including a case that accommodates a movement including a lower peripheral bearing surface, the case including a case middle to which a back cover and a crystal are respectively assembled. The timepiece further includes a clamping element including a lower retaining surface and the movement includes an upper peripheral bearing surface, the lower retaining surface of the clamping element and the upper peripheral bearing surface being in mutual contact. The back cover includes an annular peripheral shoulder, against which is affixed the lower peripheral bearing surface of the movement, which is compressed between its lower peripheral bearing surface and its upper peripheral bearing surface respectively by the annular peripheral shoulder of the back cover and the lower retaining surface of the clamping element.
