A wristwatch includes a watch body having a display unit including a seating part formed on an outer frame of the display unit, and smart glasses having a temple tip detachably coupled to the seating part to constitute at least a portion of a case body or a bezel of the watch body and surrounding at least a portion of the outer frame of the display unit. The temple tip of the smart glasses is formed in a shape corresponding to the seating part of the watch body to surround the outer frame of the display unit of the watch body while being mounted on the watch body and supported by the watch body.

Method of assembling a timepiece comprising a watch movement and a water-resistant case, the method comprising: a first stage of closing the case by fitting and securing a first case element, more particularly a back, and then a second stage of closing the case by actuation of a second case element, more particularly a stem, in particular a winding stem or a valve stem or a push-button stem, the second case element being mobile between a first configuration, in which a fluid communication between the interior of the case and an environment outside the case is permitted, and a second configuration, in which the fluid communication between the interior of the case and the environment outside the case is limited, the second stage of closing being an actuation of the passage of the second element from the first configuration to the second configuration.

The invention relates to a timepiece comprising at least an hour indicator, a minute indicator, a movement arranged to drive the hour indicator and the minute indicator, a dial, a crown and an indicator for at least one time zone, housed inside a first case. According to the invention, the first case is rotatable inside a second case about an axis of rotation, so that a rotation of the first case in a clockwise or anticlockwise direction with respect to the second case allows a time zone to be chosen and the time in the selected time zone to be indicated.

A mobile apparatus is provided that is able to equip any object of value, such as a watch or piece of jewelry, and protect it. The present mobile apparatus includes: an electronic module able to execute a mobile application, a display screen connected to the electronic module and arranged to display information relative to the mobile application, and a fastening support whereof the shapes and dimensions are arranged so that the mobile apparatus can successively equip any object of value, and to be able to fasten, removably and by superposition, at least one display screen to an object of value when object of value is attached around part of a human body. In addition, the mobile apparatus covers at least part of a surface of the object of value designed to be easily visible by the person when the object is worn.

A handheld pool game clock apparatus suited for timekeeping pool/billiard games is presented. The handheld pool game clock apparatus contains a clock body, at least one display, a processing unit, at least one switch, and a control panel. The at least one display is distributed around the clock body. The processing unit and the at least one switch are connected within the clock body. The control panel is connected adjacent to the clock body. The at least one display, the control panel, and the at least one switch are electronically connected to the processing unit.

Watch or item of jewelry including a case or setting including main and secondary slots that enable the fixture of interchangeable removable wristbands including an end link with an end piece with studs arranged to cooperate in a complementary manner with the secondary slots. The link includes a lock with a slide catch arranged to cooperate in a complementary manner and with minimal play with the main slot in a locking position, and the lock further includes a pushbutton operable by a user to move the slide catch away from the main slot and control an unlocking of the lock by retraction of the slide catch by an application of pressure to the pushbutton.

A horological calotte (200) forming a casing for a horological movement (400) according to a calibre model in a predetermined family. The movement includes a projecting control member (410) whose distal part (411) is distant from a movement axis (DM) by a radial value (VR) specific to the model. The calotte includes a ring (220) specific to the model, which is fitted in a single angular position with a bottom (210) and a cover (230) to enclose the movement (400). Its outer shape is identical for each calibre, with reference shoulders (240) defining a calotte axis (DC). The ring offsets the movement axis relative to the calotte axis in the radial direction (DR) of the control member (410), by a value such that the distal part (411) is distant from the calotte axis by a predefined value (VP) identical for all calibres of the family.
