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.

A case including a case main body, an operation member having an operation head portion which protrudes outside of the case main body, an exterior member which is detachably attached to the case main body while covering outer periphery of the case main body, in which the case main body has a protection projection provided on an outer peripheral surface such that an outward projection length becomes shorter from an upper side toward a lower side, and the exterior member has a housing portion which houses the protection projection.

An adjustable timer teaches time in a simple manner to those having difficulty understanding the concept of time. The timer displays remaining and elapsed time. The timer may be set to rotate a shaft at different speeds. A colored disk is attached to the shaft. Boards having faces with different numerical indicia reside in a cavity and may be interchanged by a user. The exposed board face corresponds to the setting of the timer such that one full rotation of the shaft and disk corresponds to the numerical indicia of the exposed board face.

A smartwatch includes case, a crown, a guide rod, and an internal mechanism case. The case is detachably coupled to an outer side of the internal mechanism case. A through hole is disposed on the case. The guide rod is disposed on the internal mechanism case and is opposite the through hole. A stem of the crown extends through the through hole. A knob of the crown is located on a side of the through hole that is distal from the guide rod. The stem is configured such that when the knob is subject to pressure, the stem approaches the guide rod, and when the knob is subject to pulling force, the stem moves away from the guide rod, and when the knob is subject to rotation force, the stem rotates and drives the guide rod to rotate.
