A watch can include a watch body and a band for securing the watch to the user. The watch body can detect an identification of the band or combination of band portions, which can serve as an input to initiate actions performed by the watch body. For example, a type, model, color, size, or other characteristic of a band can be determined and used to select a corresponding action performed by the watch body. Identification of the band can be performed by components of the watch body that also serve other purposes. The watch body can respond to the identification of a particular band by performing particular functions, such as changing an aspect of a user interface or altering settings of the watch body.

A connector including an attachment member which has an attachment hole and is provided on one of a connection object and a connection target, and a connection member which includes a slide member that has a lever and is slidable in a cylindrical member inserted into the attachment hole, and is attached to an other one of the connection object and the connection target by the slide member protruding from an end of the cylindrical member, in which the attachment member has a slit hole which is formed extending from one end of the attachment hole to an other end of the attachment hole and in which the lever is slidable.

Wearable electronic devices, such as watches, can be provided with an attachment system for connecting and releasing a removable module that interfaces with some portion of the electronic device. For example, a watch housing includes a main body having a channel for receiving a watchband and a first opening extending to the channel. A rear cover coupled to the main body provides a second opening. A unibody button is positioned between the main body and the rear cover. The button is biased against the rear cover and is moveable toward the channel to release a watchband engaged therein.

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 watch type terminal includes a main body, and a strap connected to the main body. In the watch type terminal, the strap includes one or more modules each having a specific function, and one or more partition straps having the one or more modules respectively received thereat. In the strap, the module and the partition strap are electrically connected to each other.

Embodiments of a watch can include a watch having an analog watch face, a first watch band portion, a second watch band portion and an analog watch face. The watch can include a butterfly clasp having a digital display and a circuit board associated with a controller.

Provided is a device for fastening and unfastening a watch, in which a plurality of bezels is provided and a fastening means is provided between the bezels, so that the watch is easily and conveniently fastened and unfastened in a one-touch manner, thus completely preventing the bezels from being damaged, and providing a novel structure for fastening and unfastening a wrist watch, unlike a general watch that has a fastening and unfastening structure on a watch band. Therefore, it is possible to solve problems of inconvenience when fastening and unfastening a watch band on a user's wrist because the fastening structure applied to the band in the conventional wrist watch is eliminated, in addition to offering good appearance and allowing the watch to be easily detachably attached.

A watch including a bracelet or strap and a watch case, the bracelet including a first arm in which is housed a first printed circuit portion and a second arm in which is housed a second printed circuit portion, the first arm being connected to the second arm via a median part configured to act as a seat for the watch case and which includes a mechanism ensuring electrical continuity between the first printed circuit portion and the second printed circuit portion. The first and second printed circuit portions carry at least one electronic component and an electrical energy source supplying the electronic component with electrical current.

A set of watch straps include a first strap, the first strap including a first band, a first adapter, and a first lug connected in series, and a second strap, the second strap including a second band, a second adapter, and a second lug connected in series. The first lug is configured to slide into a first strap receiving groove of the watch, and the second lug is configured to slide into a second strap receiving groove of the watch. At least one of the first strap and the second strap is reversible.

A wristwatch, comprising: a watch case (2); a clasp (3), said clasp comprising a frame (4) that can clip over the top of the watch case (2) in a closed position, and that can be unfastened from the watch case (2) in an open position; a bracelet (12), said bracelet comprising a single strand, said strand having a first end (120) and a second end (121); said first end being connected to said watch case (2) and said second end being connected to the clasp (3); a locking member (5) connected to the watch case, the locking member being able to be pivoted between a position that allows it to be inserted into the opening (40) of the frame (4) when the clasp (3) is being closed or opened, and a locking position that allows the opening or closure of the clasp (3) to be blocked.
