A device capable of being used for a long time is achieved. A power supply, a connection method of a power supply, or a connecting member, for easy attachment and detachment and non-detachment when in use, is provided. A power supply, a connection method of a power supply, or a connecting member for easy replacement is provided. A highly designed power supply is provided. Power from a battery is supplied to an electronic device through a connecting member including a pipe, a spring, and a pair of pivots. The pair of pivots are electrically insulated from each other, and electrically connected to any one of a pair of electrodes of the battery. The electronic device into which the pair of pivots are inserted includes a pair of bearings capable of receiving power.

A watchband can comfortably secure an electronic device to a wrist of a user. The watchband can include a base having a contact surface opposite an engagement surface, contact loops on the contact surface for contacting a user, and engagement loops on the engagement surface for engaging hooks. The hooks can be provided on the engagement surface, opposite some of the contact loops. The base can include base threads, and the contact loops and engagement loops can be formed by contact threads and engagement threads woven about some of the base threads between the contact surface and the engagement surface. Between adjacent engagement loops, the engagement thread can be more securely attached to the base than is the contact thread between adjacent contact loops.

An accessory includes a band member and a button. The band member includes an elongated body defining a band interior cavity containing a fluid (gas or liquid) and further includes a band contact region formed along a length of the elongated body. The button has top and bottom portions and a body extending therebetween. The bottom portion is operably coupled to the band member. The body defines a button interior cavity that is in fluid communication with the band interior cavity, and further includes an expandable mechanism that includes first and second ends and a longitudinal axis. The expandable mechanism is movable between an expanded configuration and a collapsed configuration to selectively move the button between an expanded position and a collapsed position. Upon engaging the band contact region, the fluid urges the button to the expanded position.

A wearable jewelry device is a continuous ring shaped base member including an interior side, an exterior side, and a circumferential channel defined in the exterior side, the channel having a depth and extending annularly around a circumference of the exterior side of the base member; and a continuous annular decorative band removably receivable within the channel of the base member. The decorative band has a thickness that is substantially equal to the depth of the channel such that the decorative band is flush with the exterior side of the base member when the decorative band is received within the channel. The base member and the decorative band are formed from a resilient material.

External part for a timepiece or piece of jewellery, this external part being produced by means of a polymer matrix in which piezochromic molecules are dispersed that change from a first stable state to a second stable state while changing colour under the effect of applied pressure.

An audible wristwatch assembly for alerting a blind user of the time of day and calendar date includes a strap that is worn around a user's wrist. The strap is extended through a housing and the housing has a recess therein. An electronic clock is positioned within the housing to track the time of day and the calendar date. A speaker is coupled to the housing to emit audible sounds outwardly from the housing. An announcement button is movably coupled to the housing, and the announcement button is positioned in the recess to inhibit the announcement button from being inadvertently depressed. The speaker audibly emits the time of day and the calendar date when the announcement button is depressed to alert the user to the time of day and the calendar date.

Systems and methods of providing a composite material that is bendable but substantially resists stretching under tension. One embodiment may take the form of a composite material formed by over-molding a woven glass fiber with silicone. The woven glass fiber may be rolled out with a silicon polymer melted into the woven fabric as the rolling process continues. The composite of the two materials may provide a material that bends easily but does not substantially stretch.

A watchband can comfortably secure an electronic device to a wrist of a user. A connector can be provided along a segment of the watchband to receive and secure to another segment of the watchband. For example, a connector can include a housing with an inlet and an outlet, a first pad within the housing, and a second pad within the housing. When a watchband segment between the first and second pads is moved in a direction from the outlet toward the inlet, the first pad and the second pad move toward each other to clamp the watchband segment without plastically deforming the watchband segment.

A watch strap with a plurality of quickly interchangeable, decorative plates attached to express a person's characteristic or style. The watch strap allows for the removal of decorative plates on the watch strap via manipulating a tab attached to the plates. Another variation of the invention is to depress a button, attached to the plate, beneath the watch strap. The plates may also be removably secured via a plurality of screws.

Provide is a display device. The display device includes a watchcase, a first display screen and a flexible display component. The first display screen is arranged on a front side of the watchcase. The first display screen includes a first display surface. The flexible display component is arranged on a back face of the watchcase. The flexible display component may be bent along a first direction to be reused as a watchband. Moreover, in the condition that the flexible display component is reused as the watchband, a surface of the flexible display component facing away from the watchcase is a second display surface.
