A wearable fluid-dispensing apparatus that includes a flexible wristband coupled to and surrounding a wrist-arm area of a user, with the wristband having a frame disposed along an outer surface of the wearable wristband and at a ventral side of the user's wrist, an enclosed cartridge coupled to the frame for housing a fluid therein, and a fluid transfer conduit disposed within the enclosed cartridge for transporting the fluid from the enclosed cartridge to a nozzle port on a finger-activatable pump assembly coupled to the frame. The pump assembly defines a nozzle port disposed above a top end of the wristband and angled toward the user's palm, defining a fluid extraction passageway fluidly coupled to the nozzle port and the fluid transfer conduit, and operably configured to translate downwardly toward the fluid extraction passageway fluidly to generate a vacuum therein and emit the fluid on the user's inner hand.

A wearable electronic device assembly has a strap attached to the device for attaching the device to a wearer, and a connector for securing two overlapping end regions of the strap together. The connector has first and second parts configured to be secured together with the two overlapping end regions of the strap extending between them, to secure the two end regions together. The first part has a projection arranged to extend through or adjacent to the strap. The second part has a main body having an aperture to receive the projection of the first part, and a securement part movable with respect to the main body between a released position and a securement position. The projection is retained in the aperture to secure the first part of the connector to the second part of the connector.

A watch can include a first watch band portion and a second watch band portion both configured to be coupled with a mechanical watch. The watch can further include a circuit board associated with a controller, the circuit board and controller being removably retained by a clasp. The circuit board and the controller can be electronically and operatively independent from the mechanical watch.

An end link for securing a watch strap on a watch case including a connecting piece of a wristband, the watch case having a pin. The case has a longitudinal slot delimited by two support surfaces parallel to a main plane. The connecting piece has a lateral face which includes a guiding groove arranged to cooperate in a complementary manner with the pin, and the connecting piece has a lock with a slide catch arranged to cooperate with the slot in a locking position, towards which the slide catch is moved by elastic return belonging to the lock. There is unlocking portion arranged to be operated directly by a user to move the slide catch away from said slot of the case. The guiding groove is curved so that the slide catch is firmly maintained against one of the two surfaces in the locking position.

A device for attaching a bracelet or strap to a watch case, the device including, on the one hand, a bar secured to the watch case by means of a horn, and on the other hand, an insert integral with the end of the bracelet, wherein the bar and the insert are complementary to interlock with each other forming removable assembly means to make the bracelet interchangeable. The insert includes a movable pivot mounted in the insert and arranged to engage in a corresponding hole of the horn, the device having handling means integral with the movable pivot in order to move from a first position, in which the pivot is free to move and the strand can be assembled and/or disassembled, to a second position, in which said pivot is stationary in translation and the bracelet strand is locked on the watch case.

A trigger device is provided. The trigger device includes a controller, a screen assembly, an extendible support assembly operable to support the screen assembly, and a drive assembly operable to drive the support assembly. The drive assembly is provided with a first contact, and the support assembly is provided with a second contact movable relative to the second contact. During retraction or extension of the support assembly, the first contact and the second contact move relative to each other between a contacting state and a separating state. The controller determines whether the support assembly is in the retraction state or the extension state according to the contacting state or the separating state of the first contact and the second contact, so as to control display of the screen assembly. A smart bracelet is further provided.
