In yet another embodiment of the present invention, the smart watch may include at least two actuators such as a primary crown and a secondary crown. The crowns of the watch are operated by means of a push or rotation. The primary crown is used to control the hands present including the hour hand, minute hand and the second hand. The secondary crown is used to control the display disc through the micro motor. In an example embodiment of the present invention, the micro motor is actuated by an external push on the secondary crown, wherein the secondary crown in turn enables the movement of the display disc to a preconfigured position for displaying at least one notification to the user such as date. The external push (on the secondary crown) may not be limited to single press, double press etc. Each actuation to the micro motor through the secondary crown is mapped to different notifications. The notification elements placed on the display disc include but are not limited to, date, day, sensor activity, alert, percentage, message, call/message notifications etc. In yet another embodiment of the present invention, additional information may be printed on the display dial, which are visible to naked eye only through the magnifier. Non-limiting examples of the additional information include incoming call alert or some sensor threshold alert and so on.

[025] In another embodiment of the present invention, the dial of the wearable may be illuminated by a light source. The transparent case is used to view the enlarged notifications to the user. When the actuator is triggered, the associated action is being performed by the micro motor to move the display disc to the preconfigured position and that portion of the dial is illuminated for a while to project the notification element. For example, the notification element may be projected for 10 to 15 seconds and the display disc returns to its earlier position. Further, projected notification is captured by the transparent case and the user views the projected notification through the case. In an embodiment of the present invention, the transparent case accommodates different colored light sources, wherein the duration for which the different color display is programmed in the micro controller. Typically, for a particular notification element one particular color may be used during the projection of the notification. In yet another embodiment of the present invention, the display disc may be transparent, hence displaying the elements printed on the dial.

[026] According to an embodiment of the present invention, the display disc is configured to rotate either in clockwise or counter-clockwise to reach the preconfigured position. In another embodiment of the present invention, the speed at which the display disc rotates to the preconfigured position is dependent on the rotation speed of the micro motor (rpm). For example, when the user wants to see the date, the user has to press the secondary crown once, meaning, the micro motor rotated, and in turn the display disc is rotated and the magnifier on the display disc is placed above the date (one of the notification element). The magnifier enlarges the size of the date (printed on the dial) and displays the magnified date to the user. In an embodiment of the present invention, after displaying the magnified content, the display disc may return to a preconfigured position. In other words, the magnifier is small circular shaped lens, which is part of the display disc. The display disc is rotated either in clockwise or counter clockwise direction by means of one of the micro motor. The relevant rotation of the micro motor ensures the accurate positioning of the display disc. Further, the step angles of micro motor are also preprogrammed.
