There is provided a display assembly for a wearable device, the display assembly comprising: a solar cell layer; and a touch sensor layer, wherein the solar cell layer is arranged above the touch sensor layer, wherein the solar cell layer comprises photovoltaic material arranged at an edge region of the display assembly leaving a uniform central region of the touch sensor layer uncovered.

A wearable smart device of the present invention comprises: a main body on which a basic module is mounted; a band on which at least one auxiliary module is mounted, which is selectively attached and detached to the main body made of a polymer material or a rubber material to be bent; a connector electrically connecting the main body and the band; and a coupler physically connecting the main body and the band. According to a configuration of the present invention, the present invention is possible in realizing a high-capacity and high-performance smart device.

A wrist-worn watch device includes a time keeping circuit that is powered by a first battery disposed in the body of the watch device. A larger, secondary battery is also disposed in the body of the watch device. The secondary battery is not used to power the time keeping circuit, but rather can be recharged through a connector disposed on a first wrist strap portion, and can be used to recharge the battery of a portable electronic device through a connector on the second wrist strap portion.

According to example embodiments, charging of a wireless device includes using a time-displaying power source system to transmit electrical power to a wireless receiver by inductive electrical power transfer.

A system for transforming a regular smartwatch into a luxury item, comprising, a smartwatch unit including at least the display unit of the smartwatch; and a box including a housing to accommodate said smartwatch, said box having a cover being openable and closeable to cover said display unit, wherein said cover has at least one hole so that a corresponding portion of said display unit is visible to a user when said cover is in closed position, wherein when said cover is in closed position, the smartwatch unit displays the output of the smartwatch in on said corresponding portion of the display.
