A watch system is provided, including a watchband, a lug bucket, and a puck. The watchband may include a flexible member configured to be mounted onto a wrist of a user. The lug bucket may be coupled to the electronic watch band and may include a circular ledge. The puck may include watch functionality. The puck may be configured to be removably coupled to the lug bucket. The lug bucket and the puck may have corresponding locking features that are configured to rotationally and translationally fix the puck to the lug bucket. The corresponding locking features may be configured to be engaged when the puck is translated relative to the lug bucket and rotated relative to the lug bucket by a predetermined rotation angle.

A timepiece or piece of jewelry includes a structure with a set of horns carrying a bar receiving a removable snap-hook fixed to a strand. The bar includes, at a distance from each of the points of attachment to the set of horns, a notch including two sides which limit the lateral travel of a curved beak portion of the snap-hook and limit the angular travel of the snap-hook with respect to the bar, so as to prevent any contact between the snap-hook and the set of horns to which the bar is fixed.

An accessory having a first face and a second face connected by a lateral face, the second face having a slot extending to the lateral face, forming on the lateral face a hole the shape defined by the transverse cross-section of the slot. The transverse cross-section has an open contour having a bottom and an opening connected by a first lateral side and a second lateral side, the first lateral side and the second lateral side each having a part approaching from the bottom towards the opening, towards the opposite lateral side. The dimension of the bottom of the contour are constant along a direction defined by a direction extending substantially perpendicular to the transverse cross-section and going from the hole towards an inner part of the accessory. The slot is intended to receive a fastener.
